I know when I do Contractor for wagons goods.... I tend to go 10% (by scrollbar by 9 or 10 move across) below so let say it ask for 1000 rubber, I only send 990 only as I know I can used 5min which give me that extra 10% more for me to complete the task (However this only useful if you do it after 5 mins (when it arrives to Contractor station) up to 2 hour, after 2 hour you will lose 10% bonus so therefore you only be able send 990 rubber to Contractor if u do it after 2hr).

For Non goods wagon .... erm that more tricky as I tend go over often unlike cargo wagons where I am able send right amount..... so for that I tend to go down from scrollbar by 5 or 4 move across (I get lucky if I do by 6 but not often.... 5 seem more reasonable for me for the contractor task required).

Hope this helps.

As I only know formula for cargo wagon only.
