Thank you.

Any Cal, I think what TDC20 is sayin is that:

(1) "Changing the spring from 17lbs to 22lbs only changes slide velocity by 0.06 fps" during the first 0.210-inches of slide travel, but

(2) "a 22lb spring will decelerate the slide motion much more quickly than a 17lb spring" after that.

So, the strength of the recoil spring makes a big difference in the process, but just not in the first 1/5th of an inch in rearward travel of the slide.
