I think it's a noble idea with good intention, but tend to agree with the replies in general. I'm painting with a very broad stroke here, but I don't see many respectable fast guys that subscribe to DM.
Talking about being fast isn't trying to big dick anyone, but there's no other metric in this sport to gauge ones ability. At the end of the day, lap times are the non-subjective measurement that you base things off of, which is why I don't give much initial credit when the first thing people say "Oh I'm in expert/advanced group". Well that's fine and dandy, but are you one of the backmarkers of A group or at the pointy end? Where as, if a lap record of a track is a 1:10.x, and you're running anything below a 1:15, I say to myself "Well, that guy knows which side the gas is on for sure". Because a lap time within a relative close percentage of the lap record tells anyone how much that rider is (or is not) pushing.
So after 10 years of coaching with N2, I feel I have a good idea on the riding capability of Novice/Intermediate group riders. Which, ironically, happens to be the Dave Moss fan base.
I have seen plenty of Novice and Intermediate group riders have some fucked up bikes. Blown fork seals, chains tighter than a guitar string, ergonomics all dicked up, incorrectly fitting helmets (watching riders have to slide their helmet up after a corner because it slid down and they couldn't see...), all sorts of nonsense. And this isn't even taking into consideration body positioning, lines, passing, etc.
Of all those things, tweaking suspension with some clickers isn't at the top of the list of things the rider should be worried about when they're circulating around the track at 20-30 seconds off the lap record. The slower the rider, the less it really matters. Are most Intermediate/Novice riders even capable of noticing a few clicks of rebound/comp/preload? Let's say DM corrects the suspension for that rider - is that the reason that rider couldn't hit an apex to save his life?
If he was coming with a bazillion fork and shock springs, tools to service suspension, and get an actual solid base line...I could see that. But to just look at tire wear, suggest some tire pressures, and limited suspension adjustment (within the confines of whatever springs/oil/etc are in the bike)? For $400? And at no shade against Dave, but he doesn't know what springs are in your bike, how the valve stacks are built, etc, because he can't disassemble everyone's suspension, so he's already very limited what he can adjust.
A total suspension refresh with the correct springs for your pace with an experts baseline (Pit Lane Moto, MDM, MRP, etc) isn't much more than $400 and would give the rider a much more refined starting point.
