Think you know this already but if at all possible then don't plunge ramp or spiral into material. In Both cases you want to enter quickly possible to stop heat building up in tool so use same feedrate. If you must plunge then 50% feed.

When doing the pockets I'd spiral down full depth 5mm and cut full depth with 40% step over. Why waste the flute length.?
