No sure if this has been done yet:
There are lots of areas in the game where timing is ever so important and since Jump Man moves at a consistent pace these timings never chaneg. This is just one.
Attached is a picture at the start of the board showing the conveyor moving left with the left hand edge of the pie in the middle of the bottom right ladder. This is the last position the pie can be for Jump Man to safely move up ladder; one frame more and he won't make it. If you do go up in this position, however, you can't jump the pie straight away, you need to move a fraction left, then jump.
Hope this helps someone; it helped me make some judgement calls.
