Well, yeah, John, mostly I agree and standby that
sentiment. For most of us, using 100% levels based on
Sustained G's will yield more useful information. I only
suggest going to Absolute Peaks when you start to score so
high that Sustained Peaks aren't giving you the learning
info that you need.
Maybe soon we'll all need Absolute Peaks!
The second factor is that the M3 has the suspension of a
jelly donut. Okay, it's a really sophisticated, incredibly
well-handling jelly donut. But it's a jelly donut
nonetheless. So if the parking lot is smooth enough, the
driver is adept enough, the jelly donut will absorb your
minor surface variations and bumps and hide a lot of the
little warts that might otherwise exist if you were driving
a "real car", like say, a Corvette for instance.
(Whew, was that too politically correct?)
So to drive a softly sprung jelly donut vehicle well enough
to need to use Absolute Peaks takes one heckuva lotta
talent. And it's even tougher with a stiffly sprung sports
car.
