I got a Manual Check from Delta and the description is RECOG. The Paycheck codes has nothing on it. Anyone know what this is for?

Also if I add up my FLT ADV and my FLT PAY and multiply it by 5% it comes out to a number that is LARGER than what was paid in the October Profit sharing payment. I take it the FEB will be whatever was missed since the OCT one was just a guess?
