Sorry to be rude, but you have disparaged opensocialsecurity.com before and I don't think it is warranted or helpful to people looking for resources to understand their SS benefits. It is a fantastic program that has been tested by many people. I've used it to help me understand how the formulas work, much easier for me to see the numbers worked out than to read the "word problem" description on SSA.gov.
Meanwhile I recall from another thread and I see you repeating the same data here - you never discuss your PIA, just your benefit. You need your PIA and the month you claimed to run the program. You can work out your PIA if you have your birth month and year, the month and year you claimed and your current gross benefit using the various formulas on the SS website. But you cannot go by your memory of what it was, memories can be wrong, COLAs get applied, etc.
Last time you started in on this, I saw that someone forwarded a link to the thread with your criticism to Mike Piper, the SS expert and author of the program on a Feature Request/Bug Report thread over on Bogleheads.com. I believe he responded that he couldn't help without actual data.
