For those wondering what this chart is Ellen White mentioned, it is referring to the chart the Millerites made up showing the prophecies which pointed (to their minds) to Jesus coming in 1843:
I have seen that the 1843 chart was directed by the hand of the Lord--Ellen White, Early Writings, page 74
Goodness, your continuing to take EGW statements out of context and apply a false interpretation to what they are saying this is a shame to you.
The way you have written this is to say that this statement above is in reference to the 2nd coming and God wanted to decieve everyone.
Here is the context provided below and what you left out of your statement and interpretation added to it...
"I have seen that the 1843 chart was directed by the hand of the Lord, and that it should not be altered; that the figures were as He wanted them; that His hand was over and hid a mistake in some of the figures, so that none could see it, until His hand was removed."
..........
This applied to the chart used during the 1843 movement, and has special reference to the calculation of the prophetic periods as it appeared on that chart. The next sentence explains that there was an inaccuracy which in the providence of God was suffered to exist. But this does not preclude the publication of a chart subsequently which would correct the mistake, after the 1843 movement was past, and the calculation as then made had served its purpose.

What did the 1843 movement represent?
Types and Anti-types
There were seven festivals in total. (See * Leviticus 23)
The last three ceremonial feasts which included the Feast of Trumpets, the Day of Atonement, and the feast of Tabernacles all point towards 1843, 1844, and the Day of Judgment respectively.
Trumpets in the Bible are used to symbolize loud warnings or cries that have to do with judgment (Exodus 19:13;16; Lev 25:9). This was fulfilled when William Miller warned the world about the coming of the Lord from
1833 to 1843.
In the Levitical annual festivals 10 days prior to the Day of Atonement and the Cleansing of the Sanctuary commenced the Feast of Trumpets. This was a solemn occasion that was to prepare God's people for the Day of Atonment where trumpets were to be blown each day for 10 days at the sin offereings.
LEVITICUS 23:24-27
[24], Speak to the children of Israel, saying,
In the seventh month, in the first day of the month, shall you have a sabbath, a memorial of blowing of trumpets, an holy convocation. [25], You shall do no servile work therein: but you shall offer an offering made by fire to the LORD. [26], And the LORD spoke to Moses, saying, [27], Also
on the tenth day of this seventh month there shall be a
day of atonement: it shall be an holy convocation to you; and you shall afflict your souls, and offer an offering made by fire to the LORD.
10 Years 1833 to 1844 (10 Days/Years of Blowing of trumpets)
Miller first published series of articles on his prophecy findings
locally on the May 15th 1832. In following summer of 1833 due to responses from these articles Miller writes;
"
One Saturday after breakfast, in the summer of 1833, I sat down at my desk to examine some point; and as I arose to go out to work, it came home to me with more force than ever, "Go and tell it to the world." The impression was so sudden, and came with such force, that I settled down into my chair, saying, I can't go, Lord. "Why not?" seemed to be the response; and then all my excuses came up, my want of ability, etc.; but my distress became
so great, I entered into a solemn covenant with God, that if he would open the way, I would go and perform my duty to the world. "What do you mean by opening the way?" seemed to come to me.
Why, said I, if I should have an invitation to speak publicly in any place, I will go and tell them what I find in the Bible about the Lord's coming. Instantly all my burden was gone; and I rejoiced that I should not probably be thus called upon; for I had never had
such an invitation.
In about half an hour from this time, before I had left the room, a son of Mr. Guilford, of Dresden, about sixteen miles from my residence, came in and said that his father had sent for me, and wished me to go home with him. Supposing that he wished to see me on some business, I asked him what he wanted? He replied that there was to be no preaching in their church the next day, and his father wished to have me come and talk to the people on the
subject of the Lord's coming." (William Millers apology and defence 1845 p 18-19)
Just as the trumpets in the bible are used to symbolise warnings 10 years/days prior to the fulfillment of Daniel 8:14's 2300 year/day prophecy in 1844 just like in the type where the trumpets were blown 10 days prior to the Day of Atonement, The message of the 1st Angels message (Revelations 14:6) and Christs immenant coming became a world-wide message and movement at the time.
Trumpet message was a world-wide message across many churches
...
"
In the type the trumpets were blown throughout Israel, warning all of the near approach of the solemn day of atonement. In the antitype we should expect some world-wide message to be given in trumpet tones, announcing the time near when the great antitypical day of atonement, the investigative judgment would convene in the heavens. Beginning with the years 1833-34 and extending down to 1844, such a message was given to the world in trumpet tones, announcing, "The hour of His judgment is come.
"William Miller and others, in their study of the declaration in Dam 8:14, "Unto two thousand and three hundred days; then shall the sanctuary be cleansed," found that this long prophetic
period would end in 1844. They failed to connect this text with the ancient typical sanctuary, but applied the term "sanctuary" to this earth, and taught that in 1844 Christ would come to the earth to cleanse it and judge the people.
William Miller was joined by hundreds of other ministers in America, who proclaimed his message with great power. Edward Irving, with many other consecrated men, preached the
205 same in England; while Joseph Wolff and others heralded it in Asia and other portions of the world. During the ten years preceding the tenth day of the seventh month (Jewish time) in 1844, every civilized nation on the earth heard in trumpet tones the announcement of the message of Rev.14: 6, 7, "The hour of His judgment is come."
This message was due at this period of the world's history. Paul in his day preached of a "judgment to come," but the burden of the message given during these years was, "the hour of His judgment is come."
The fact that the men who proclaimed this message misunderstood the full import of it, did not prevent their fulfilling the antitype of the ancient type.
When the followers of Christ cried before Him, "Blessed be the King that cometh in the name of the Lord," and spread palm branches in the way, believing that Jesus was entering Jerusalem to take the earthly kingdom, they fulfilled the prophecy of Zech. 9: 9.
If they had known that in a few days their Lord would hang upon the accursed tree, they could not have fulfilled the prophecy; for it would have been impossible for them to "rejoice greatly." In like manner the message due to the world between 1834 and 1844 could never have been given with the power and joyfulness demanded to fulfil the antitype, if those giving it had understood that the Saviour, instead of coming to this earth, was to enter the most holy apartment of the heavenly sanctuary, and begin the work of the investigative judgment.
God hid from their eyes the fact that there were two other messages to be given to the world before the Lord should come to the earth in power and glory (Rev 14:6-14)" * The Cross and its Shadow; SN Haskell p. 120-122

The quote you provided above sounds a bit different once the context has been provided doesn't it?
The was a reason the calculations were hidden by the hand of God in the 1843 chart as stated from the EGW statement you provided.
"I have seen that the 1843 chart was directed by the hand of the Lord, and that it should not be altered; that the figures were as He wanted them; that His hand was over and hid a mistake in some of the figures, so that none could see it, until His hand was removed."
The 1833 to 1843 movement was for the fulfillment of the type of the Feast of Trumpets.
..............
Based on the 2300-day prophecy, he predicted the world would end as Daniel 8:14 says, “then shall the sanctuary be cleansed.” When this date did not materialize, it was realized that they had miscalculated the BC/AD switch, as they realized there was no ‘0’ year.
The dates were then recalculated and it was realized that this prophecy pointed towards 1844, not 1843. Again the message of judgment went to the world. When this date also did not materialize, most followers of the message fell away, but a few remained and through diligent study, they were lead to recognize that the prophecy points towards the heavenly sanctuary, where Jesus is our High Priest in the tabernacle that the Lord pitched (Hebrews 8:1-2).
William Miller got the date right but the event wrong. The Day of Atonement was not pointing towards anything on Earth, but rather to the cleansing of the heavenly sanctuary in 1844. The last ceremonial feast—the feast of Tabernacles—points towards Jesus return, when He comes to fetch His children.
Your quote is taken out of context and you have applied a false interpretation to what it is saying.
Hope this helps.
