There is a half way point of 1260 days. But that is really not the issue of your not being clear.
Revelation 13 actually says the beast rules for 42 months. Which the beast receives power from Satan.
I do agree with you that the Amil position about the 42 months is wrong.
The purpose of the kings of the earth gathering their armies at Armageddon is to stop Jesus's Second Coming, from Him executing judgment on them and all responsible for martyring the great tribulation saints.
Jesus ends the 42 months rule of the beast at Jesus's Second Coming in Revelation 19, by having the beast and false prophet cast alive into the lake of fire, and Satan into the bottomless pit.
The seven vials of God's wrath are spread across approximately the final quarter of the seven years.
The 7 vials of God's wrath, as they are occurring, would be an indication that Jesus's Second Coming is rapidly approaching. But the sign of Jesus's Second Coming will be the sixth seal event, the sign of the Son of Man in heaven - 45 days before Jesus Returns down to this earth.
The rapture will take place years before the 7 vials of God's wrath take place.
The Aod for 1335 days (Daniel 12:11-12). Satan will be cast down to earth for the remaining time/time/half time of those 1335 days. The time/times/half time will be a little bit less than 1260 days to account for the war in the 2nd heaven time.
For that time/times/half period, Satan will possess that Aod statue image making it appear to come alive, speak, and the false prophet demand everyone worship it.
Which everyone who worships the beast or his AoD image will drink the wine of God's wrath, Revelation 14:10.
Look at my chart, and then tell me what you are talking about from it. Satan's time/times/half time that he will have left is in blue. And the beast's 42 months is in brown. They overlap each other.
Paul does not separate the rapture from the Second Coming. That is the whole erroneous view of modern eschatology, that is wrong about futurist, dispensationalist, and the whole left behind ideology. No one is left behind period. Those left on earth who thought they were Christians, will embrace Satan by being strongly deceived.
There is only one 1260 day period of the AoD. The AoD is your AC/beast. That 42 months starts in the midst ot the week of the sounding of the 7th Trumpet when Satan is cast out. There is no FP, nor time of the AoD until after the 7th Trumpet sounds.
So the only time of GT tribulation is between the 1st Trumpet and the 7th Thunder. The GT is not the 42 months of AoD. That is why the AoD cannot come first. That 42 months ends at the moment the 2 witnesses are killed. There is only the 3.5 days they lay dead on the street in Jerusalem. The Sunday morning they are given life and ascend, is the day of the 1 hour of Armageddon.
Armageddon is not to prevent the Second Coming. That already happened at the 6th Seal. Armageddon is to remove the rest of Adam's flesh, toss the FP and beast into the LOF, and bind Satan for 1,000 years. All power of Satan and that government stopped after 1260 days, then the 2 witnesses were killed.
During those 3 days, the 7 vials are poured out, and God gathered the armies to Armageddon. Revelation 16:14-16. Notice it is the 6th vial of God's wrath:
"For they are the spirits of devils, working miracles, which go forth unto the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty. Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walk naked, and they see his shame. And
he gathered them together into a place called in the Hebrew tongue Armageddon."
The spirits came out of the mouth of Satan, the FP, and the beast/AC, but it was He/God who gathered and made sure all of humanity left on earth arrived at Armageddon. This is the wine press 42 months later instead of at the end of a week, and the winepress of Revelation 14. If the week is split in half per Daniel 9:27, then 42 months and Armageddon. If the 7th Trumpet is not interrupted, and the week is not split in half, then all those humans are killed in Revelation 14 instead of 42 months later at Armageddon.
You call the appearing of the sign per Matthew 24 a 45 day warning? Revelation 11 is talking about the 7th Trumpet, because the 7th Trumpet was announced in chapter 10. The 7 Thunders happened in chapter 10. The 6th Trumpet and 2nd woe, ended before the 7 Thunders. You do not even account for the 7 Thunders, as if they are not supposed to happen.
