On the other site you posted dates on, (just spent about an hour reading through your threads there),
at least there you asked others to ignore your posts/dates/
after you realized the difficulty you had with
all the variables (you listed several) unknown or unable to verify.
I don't think it would be helpful to repeat 5 or 10 or more pages here. As far as I can tell, no one would benefit.
(even though some of your information was interesting and possibly could stir some to investigate the Scripture, which most ignore; so that would be good,
but not this topic/thread here).
Your attempts to set dates for when adam sinned, and when the last day is, and other dates,
using as you noted what are known unapproved sources to try to set dates and other information, (misleading ones),
means
that accurate and good and unchanging results
cannot be obtained.
In computer programming, I think it was called gigo.
When you started with information in error,
you could not come to conclusions that are right.
Others are certainly welcome to look into those other threads and posts if they like.... but it is awkward saying so, because of the other posters there who willingly and maybe knowingly were leading away from Scripture,
though a couple , including you, appeared to be trying to keep things within Scriptural bounds,
except as noted the outside sources you relied on.
