Question about credit:

For tests on my one machine (unhidden in preferences now https://milkyway.cs.rpi.edu/milkyway/results.php?hostid=803986&offset=0&show_names=0&state=4&appid=), which is a v1 2665 Xeon (down clocked for lower heat) Separation takes 18k seconds for 227 credit (not overbooked) while N -Body is about total CPU of 10k-12k and running between 35-44 credit.
Since credit is based on total run length, and not CPU run time, at some projects; as a test, I over booked the 16 thread N-Body so the run time averaged about 9k seconds (5k to 18k run lengths) and the credit didn't \vary from the aprox. 40 credit on the first, normal, N Body test runs (about 1300 second run times).

Shouldn't an N Body that comes close to 1 core usage have similar credit to Separation WU's?
On average this machines N-Body (overbooked) give about 65 credit per 18k seconds CPU usage while Separation gives 227 credit per 18k CPU usage.

I search the forums for this discussion but not even the Google based search seemed to find a prior discussion.
