Optimize pocket

[MARIOBASZ]

In aluminum, for the grooving operation (the entire diameter of the cutter is in contact with the material) I use a speed F equal to, for example, 70% of that used for profiling (only a percentage of the cutter is in contact).
In the pocket operation, at each level change, grooving is performed; in the rest, outlined.
I can think of two alternatives to optimize:
1- Reduce speed at each level change
2- Modify the route, so that instead of discrete level jumps, they are gradual (spiral silhouette) until the penultimate pass.
I don't know how the traditionals software generates it.
My preference is for the second alternative, I sense that it will have a better surface finish

I've made progress in pocket spiral mode
POCKET SPIRAL.TXT
1-Traditional pocket: in each pass, the cutter makes a cut with the entire diameter

2-Spiral Pocket (need to improve equidistance in the points of the spiral)

3- Overlay images
