His OAR was perfect, I ran into him at national trails last month, elevation 800ish and DA was about 3200 that day. I loaded my AO tune for my next trip there and ran a 12.61 in similar DA.
He emailed me a log and it looked pretty similar to mine. Only thing that stuck out to me was his 0-60 mph time was 5.3 seconds and mine is a hair under 4.3 seconds. As far as why, that is the great mystery.
