Range 2 Overrev's

Range 2 Overrev's
I had a PPI done on a car (2003 C4S), and it was reported that it had 282 "range 2" overrevs. It has 66K miles on it.
Does that seem like a lot? From what I understand, that means that the spark plugs fired 282 times when the engine was overrev'd, probably from a missed shift. The place that did the PPI said that if the valves were damaged, that there would have been other signs that they would have noticed.
I'm sure that the PPI advisor is correct, but I just wanted to get a second opinion.
Thanks for your help.
P.S. I did search on the topic, but I couldn't get the forum to search for "range 2" together instead of posts with range or 2 that might be separated.

Some P-tech guru correct this if it is way off, so we don't promulgate wacky info.

When an engine is replaced whatever data stored in the DME remains. The DME is not replaced or zeroed out due to an engine replacement.
The opposite is also true. When my DME in my 1997 Boxster was replaced 3 years ago the DME started with zero engine operating hours, and zero range X revs.

EDIT: Oops, my bad. The guys must have missed a downshift or spun out the car and ran in reverse with the engine running forward, I guess.

The sheet says:
Number of ignitions, range 1
3658 1588.0h
Number of ignitions, range 2
282 1587.8h
Operating hours counter
1590.0
So, range 1 seems fairly low for a car with 66K (but I am only comparing that to examples that I could find on the internet).
Thanks again for the advice.
