Yeah.... I asked too...many times
Timeslips were not mixed up.
The car number is entered to the lane, and appears on every slip you get.
It was the first thing I checked.... and yep, was my car/entrant number on the slip, and every other slip I got for the day.
The diff wasn't behaving like an open diff that day. I went over the video many times, and every warm up burn out was twins....
Mind you, the diff died a couple of months later, so maybe that was an early warning or something.
And I hardly think the officials, crowd, or driver in the other lane would allow me to get away with staging with the rears on the line!
