Fred YI can assure you that 90 day-last second FB thing is NOT foolproof!! I used to think it WAS--and it SEEMED to work a couple years ago.
My only Neg is a Retalitory from a NP Bidder who I left a Neg for at the last second of the 90th day!! 2 days later he was somehow still able to Neg me back and I was able to make a rebuttal.
I've never trusted it since!
