Prospective 987.2 Cayman S... How troubling is this Over-Rev report?

People are commonly confused by this. The answer is that the ranges are not cumulative (other than the 2-range over-rev report found on 996 models). So what happens is the engine zooms past Range 3 quickly on its way to the higher ranges, then zooms back down through it once they push in the clutch and revs fall.

I bought my 2010 non-S with 51 ignitions in range 6. However, in my case, they were hundreds of hours in the past from when I got the car. For that reason, I had less to worry about. I guess the question would be, what's the time threshold you feel comfortable with - you have about 100 hours, which is relatively recent. On the other hand, as TMc993 noted, the time spent in that range was VERY short. Probably not long enough to do anything significantly bad?
In the end, if the deal is good, then it's worth looking further. The PPI will help reveal the overall treatment of the car, as well. Overall, I wouldn't say this is a non-starter... I would recommend getting a better deal, at least.
Also, as questioned above, you can get this info from the Foxwell NT530... a low cost scanner that can do quite a bit on the 987.2 platform.

just so everyone knows...when i bought my foxwell, i was issued ONE free supplemental software package with the purchase. i chose the porsche specific package and without it, the over-rev info is unavailable, AFAIK.

It could be fine, or it might not. Only time will tell. The main thing is that the ECU will always bear the scar of that over-rev, even if no damage was done. And that will mean a lower resale value down the line. So it really depends on what the PPI uncovers, and what kind of deal I can negotiate with the seller.
Would anyone say that if a 4 > 1 downshift caused this it would be worse for the car than a 5 > 2 downshift? Or is everything equal on that front?

Yep, exactly.

A second point to mention regarding resale.. I get it. But I'll be honest, I can't imagine ever selling my 987.2 - I love it that much. If it ever goes, it's going to be dead or beyond repair for some reason, at which point a range 6 is really not a big deal, haha.

will either have a rod knock or potentially reduced oil pressure. The good thing about the 987.2 is the oil pressure system exceeds requirements so
as long as compression is good and at + 100hrs. no rod knock and good oil pressure, you're probably ok.

Tiiger, Thank you for passing on this one. Drove her home today, and this car is a blast!!!
We shall see if she can sustain. I went with longevity in over rev as my ultimate decision to pull the trigger.

Congrats!
