Out of maybe 500 commercial flights I've had two RTOs, which I suspect is probably higher than the average.
One was apparently an airspeed indicator discrepancy (at maybe 60 kts), the other was after about 2 secs of rolling and probably was some configuration display issue.
Oh, and I've done one myself in a Cessna because my seatbelt was trapped outside the door and started flailing away. Won't do THAT again
