Another part of this mental torture is that you have to use a few set cuts or the machine will not realise where the top of the material is..... God, I'm not explaining this well - so here are my toolpath depths:

first pass 1.5mm (d), 2mm (f)
second pass 4.5mm (d), 2mm (f)
third pass 7mm (d), 2mm (f)

This results in the plug being the inverse of the pocket. Same applies to cleaning this up, pick out the bits and fuzzies with a razor blade.
This is a good video that explain the gap in detail.
