The spring has always gone in the same way, the more tightly would coils at the spring guide end.

I heard about this theory, but when I tested it (with both springs) the results were the same.

1.05/100, 0.64/90

The gun could be creeping a bit, haven't chronoed on 0.2s to be fair.

Specs change but SP90 seems irregular at one end...

slightly tighter at one end than the other

so you "should" have got some difference

compared to a regular spring...

(which should be same either way round)

Some other irregular springs are tighter in middle

AND one of the ends are tighter than the other...

Honestly the way the spring is fitted can make a difference

(as said I've flipped a spring to squeeze another 10fps more than once)

The SP90 or SP100 should just be tighter at one end

so should have made some slight difference

BUT like I said specs can change and be a different spring

or most likely just them qwirky airsoft gremlins

as said these spring/power stuff doesn't always follow logic

Probably why Mr Spock doesn't do airsoft

(his ears would be stinging as easy big target)

you got it sorted & that's all that matters

Yep, I am definitely gonna experiment more with this irregular spring theory. I've heard it in the past but never got to "play" with it.

SP100 is done but I still have the SP90 and I can always buy another SP100  after all it's €7.50, won't lose my sleep over that amount, plus having an extra spring in my spare parts drawer is always nice.

i just thought it was funny to cut a spring and gain power
