My conclusion would be that your fuel dilution is much higher than the "fuel dilution" reading suggests. I've seen this a lot with Blackstone reports – they show zero fuel dilution when the viscosity and/or flash point say otherwise. In your case, it shows more than zero, so I suspect the actual number is higher – especially given how low the viscosity is. That might also explain the slightly elevated iron wear.
For street use to come anywhere near track use in terms of wear potential, you'd have to be abusing the hell out of your engine. Burnouts, donuts, launching and redlining the first two gears at every traffic light, free-revving to redline, going too hard when the oil is cold, etc. High throttle and RPM at low speed, a lot. If you were to drive fast enough on the street to mimic track use in this car, you'd get arrested or killed long before your engine wore out.
