Other than a longer cylinder, I have put my s200 back to normal.
From 155 to 100 I get 50 shots slowly increasing, flattening out then decreasing. The fps goes from 770 to 790 and back down.
The fps deviation of the 40 in the middle is no more than 5, most 3 or less.
Will adjusting things extend and flatten out the curve?

I've no experience of S200 but I'd guess, "No."
Hopefully someone who is more qualified to comment will give you an answer... and I don't mind being proved wrong (but I doubt it will be different)!
