Greg - the ACD computer just goes off of calculations and readings. In reality it is fluctuating between many different calcs in each setting, it was just easier to explain using its theo. parameters. Rather then Snow 80/20, 90/10....and everything between.
Does that help more?

No. Why would it?
You still are dragging around all the same weight. Takes the same amount of power, and you still are using all 4 wheels.

Setting F R
Tarmac - 50/50
Gravel - 75/25
Snow - 100/00
The settings do work, I have have had my Evo for a winter now, and on the Advans at that (yes I am crazy, and I am not doing that again - all-season tires this round). But the car will behave closer to a FWD in the snow setting when you are in snow. Makes it easier to drive around, but it will understeer more.

I'm currently going to school in Big Rapids, MI and its already started to snow, this is my first year owning my evo and I actually still have my summer tires on (I've been lazy, gimme a break 
) and I have DEFINATELY noticed a difference in driving in the snow with tarmac compared to snow. Unless you want to be doing awd "burnouts" go with the snow setting

redfoxny be careful with the advans in the snow. As long as your not dumb they are fine, but dont even think about hitting boost just a warning, have heard of soooo many people wrecking their evo's in the snow with advans. I took my 04 to the mountains for snowboarding several times and never had a problem but I took it really easy.

SmikeEvo,
Thanks for the explanation of F/R splits.
I ran an autocross in the rain on sealed asphalt and left the car in tarmac on the first 2 runs. Times were 63+ seconds.
On my 3rd run I changed the settings to gravel. I didn't really feel any difference but my time dropped to 60+ seconds. The settings were very transparent and I just went faster.
AWD rocks inthe rain!

A little off topic, i know....buuut
Last night was the first time i had the evo out ion the snow...not much, but a few centimeters. I'm waiting on my winter rubber, as i havent gotten the delivery yet. Anyways, that left me with the stock Advans. I've alwas heard around the boards that they stockers suck in the snow, but i never realized how bad they actually suck.
My car was all over the road...and stopping, that was an adventure all in itself. Just a warning to everybody that hasnt got to put winter tires on, or people trying to run summer performance tires all winter....Get all seasons...nobody likes to see EVOs in ditches.
on a side note, i did have the ACD on the 'snow' setting...didnt really notice a difference. But then again, that could be because i was focused on the road, and staying on it.
