Bluhduh Shim stacks on 04 KTM/WP 48MM's - 200 EXC

Just curious if we have anyone on this board - which I much prefer to KTMtalk - that has experience with suspension tuning on older (2004) KTM two strokes. I've done a ton of reading, ordered a bunch of shims and hope I have a decent formula for re-valving. Any second opinions appreciated. This is my first foray into suspension tuning, and I'm going all in.

170lbs no gear, racing b-class hare scrambles on black dirt with roots and rocks. Looking to soften the famously harsh, stictionee (new word!) WP forks. But also retain some bottoming resistance since they throw a few big jumps in our mostly technical woods courses. I removed my third bush and spacer, might do the hole drilling mod if needed, I have .42 fork springs and 88-250 shock springs

Thinking I'll build my shim stacks as follows, race on Sunday! This came from reading a lot of old posts and getting a bit of direction from KTMLew:

140mm oil height

BV:
24 x .1 (2)
20 x .1 (1)
18 x .1 (1)
16 x .1 (1)
14 x .1 (1)
12 x .1 (1)
9 x .3 (1)
18 x .25 (1) - don't some say to get rid of this one?


MV:
24 x .1 (4)
18 x .1 (1)
14 x .1 (1)
11-xx to get float to 1.2mm
13 x .1 (1)
15 x .1 (1)
(2)18x.10
light spring<48600059>

Rebound:
2 deltas
16 x .1 (1)
1 delta
20 x .1 (1)
18 x .1 (1)
16 x .1 (1)
14 x .1 (1)
13 x .1 (1)
12 x .1 (1)
11 x .1 (1)
9.5 x .3 (1)
16 x .25 (1)


This is what I found when I took the forks apart a week ago, two years after a bad experience with a local suspension tuner and racing a very harsh bike during that time:

BV:

24 x .1 (3)
21 x .1 (1)
24 x .1 (2)
22 x .1 (1)
20 x .1 (1)
18 x .1 (1)
16 x .1 (1)
14 x .1 (1)
9 x .3 (1)
18 x .25 (1)


MV:
24 x .1 (4)
22 x .1 (1)
spring

Rebound:
4 delta's
15 x .1 (1)
20 x .1 (1)
18 x .1 (1)
17 x .2 (1)
14 x .1 (1)
9.5 x .3 (2)
16 x .25 (1)
