We just ran tests with my G25 and my friend's G27, and both were just about identical. The G27 shows 1 ms faster first move, my G25 stopped 9 ms faster when changing directions, and started moving to the other direction 5 ms quicker, so very small differences all-around. Note: His G27 had MUCH less resistance and a higher top speed than the archived G27, suggesting that maybe the G27 in the archives was tested with some damper? EDIT: The top speed was just about identical, the newer, less worn G27 was under 5% faster when both were tested at 107%. At 100% they were equal.
