I've heard this opinion echoed elsewhere, along with the theory that most people who have noticed this "effect" in actuality fixed some other compression issue while flipping the polarity of the spring.
I'm willing to accept experimental evidence that contradicts my findings if there's some other explanation (relating to perhaps porting or AoE or something), but for the moment, the reversed non-linear spring theory holds absolutely no water for me.

To nit-pick...and only doing so since you seem to fiddle with a lot of guns...there shouldn't be any difference in
compression but rather a difference in resultant FPS of the BB. I know that's what you meant though.
Interesting. What was your test setup, with what power springs? What differences did you get with what springs?
I've definitely seen the results of flipping non-linear springs. What I observed was that the difference will depend on the barrel length and power of the spring primarily. Also the types/makes of springs mattered too. Some have dramatic differences in the spacing/grouping of the coils and others were pretty marginal. Non-linear ones with packs of coils at either end behaved a lot like linear springs so far as flipping them around. Thinking back I definitely notice a very wide range of differences...from as little as "might be just a different airseal this assembly" to 40fps.
(One AKS74U...tiny inner barrel...had some pretty dramatic differences)
I haven't tested this stuff for stats in a long while...just hasn't been worth it.
IIRC...the Modify S110+ has quite a tight pack of coils on it
