Fastest Sneak Build?

[bward76]

I am currently on my 8th life of my completionist project. Doing Rogue Stick build 13/6/1 Rogue/Monk/Druid and realize that it may be the fastest possible consistent Sneak movement speed in the game. I know a sprint boost barb split would give you 20 second faster sneaks, but am interested in all the time sneak mode speed in which case the 10% ninja enhancement outweighs a barb splash.

Please help me out on the math if you know better on how sneak movement stacks. I am not sure if it all adds up then cut in half for sneaking or if all or part stacks multiplicatively. The only info on sneak speed I could locate is the link below which seems to point to additive then a 50% sneak multiplier reduction.

Additively:
100% Base movement
10% Monk Base movement
10% Acrobat Base movement
10% Ninja I Sneak Bonus
50% Faster Sneaking IV Rogue Enhancement
30% Striders
-------------
210% / 2 (for sneak mode reduction) = 105% consistent sneak speed in quests.


Multiplicatively:
1.0 Base movement
1.1 Monk Base movement
1.1 Acrobat Base movement
1.1 Ninja I Sneak Bonus
1.5 Faster Sneaking IV Rogue Enhancement
1.3 Striders
0.5 Sneak Mode Reduction
-------------
129.8% consistent sneak speed in quests.

I will test this out as I obtain the levels with this character. In the mean time please chime in if you know how fast this character will actually sneak.

Does no one know how exactly sneak stacks? As I level up my character I will test out the faster sneaking. I've searched the forums and found only a handfull of non-validated claims.

It seems as though some base speed stacks as addition others as multipliers:
(100% base + Monk 10% + 20% striders) * 0.5 sneak mod * 1.1 faster sneaking.

I will need to do some sneaky race times.

Ultimately I wish to end up with a character that can sneak faster than others can run with 30% striders. This appears possible (or very close) with the above build options. This would allow me to stay sneaked throughout PUG runs without falling behind.
