at my company (737NG's) we have had to do manual loadsheets anytime there was 1000kg difference with planned - even 500kg for a 6 month period. Now - after a tailstrike incident - we have to do them every sector and only *after* boarding is completed and the purser lets us know the exact pax distribution! So then the pressure is on as the ground handler is waiting ( sometimes impatiently
) Hopefully all will be solved when the ompany pays for an automated version - promised within a couple months!
