An interested party brought up the usage it's received while still in the break-in period.
I don't deny having autocrossed the car while it was "green" - at its first event it had about 200 miles on it. However, for those not familiar with autocross, a "run" is a much more brief and low-stress thing than a lap at the track. I'd even say it's lower stress on the engine and driveline than a run down the dragstrip. We rarely can use full throttle and don't spend much time at high RPM.
Here's a run at a practice event where I had speed and RPM telemetry:

Just checked my Youtube channel, looks like I have 16 videos of 370z runs there, so like 1/5 of all the autox runs it's taken you can see for yourself
