I now have 3 machines running for the WCG effort. The last machine added has been chugging away for at least 6yrs (office use) & is a 733Mhz AT/AT Compatible with 500kRam and Win2kPro OpSys. The other 2 machines are 1.8Ghz and 2.8Ghz dual core machines with large Gb rams and hard drives.

The small machine was first loaded with a Clean Energy wu, and it took ~152 clock hr's / 128 cpu hr's vs the ~ 10-11hrs/wu on the Gb machines. Since 156hrs seem a 'bit' long, I switched to NRW after the Solar completion. The small machine now cranks out a respectable 3-4wu/da taking ~7.5-8.0clock / 7.00-7.03cpu. which seems very reasonable to me (the Gb machines produce 6wu's each/day)

I never expected to receive the same credit for the lengthy Solar unit, however, I'd like to know WHY I'm only getting 8.9-9.1 / 6.5-8.3 (Claimed/Granted) credit vs ~50-75 / 61-71 credit on the faster machines???
The average Granted Credit/hr on 1.8Ghz=8.8 & 2.7Ghz=9.7 while the 733Mhz is barely 1.0!!

The ratio of speed is ((1.8Ghz+2.7Ghz)/2)/7.3Mhz = ~3 multiple.
The ratio of credit is ((325+32/2)/36 = ~8.8 multiple.

Was some HUGE handicap set in place with the extraordinary time spent on that 1st Solar unit that will effect future credit on this machine, or does something have to be reset somewhere to bring these ratio's more in line??

(Please forgive ignorance.... I have only been in WCG since Dec.08, and I've read all the forums I could to ascertain an answer to my curiosity. Asking is sometimes the shortest way to an answer.)
I appreciate your time on my behalf, and await your reply.
