Definatly a consistancy throughout the SP range, all scoring very near eachother.
Interesting to see the SE3, didn't get up to speed there Lewis, did it seem slower than the others or not?  Mine averages around 2600 steady. Peaks well over 3000 so something went wrong there.
The one thing I want to see is how slow you can get the SP6, please Lewis  I did ask
The SP4 looks a little slow for a G&G version, maybe it's not run in enough yet? although consistant for the SP range. The SP5 did almost the same as mine, did pretty well, considering the bigger/heavier flywheel too!

My SE3 went about that slow, surely you can get it much slower than that?
