1) Thanks posts should be sent in a PM
2) If the spreadsheet is culpable to user error, why wouldn't individual posts be culpable to the same? You'd be better off doing what the spreadsheet says (assuming there's nothing in the thread actively convincing you to disregard it) and posting something if/once you disprove its results.
Thanks I did check the spreadsheet, and it showed a ~60 dps increase, but I just wanted to ask here in case anyone else was in a similar situation. The spreadsheet can be trusted, but it suffers from the possibility of user error, so I like to try to double-check when I can... Thanks again!
