Does it make logical sense that the added weight calls for a slightly lighter spring?

The Super 9 uses the same recoil spring as the 4506 "wadcutter", #200710000. Any reason it shouldn't be good in a 952?
I don't have one to test but I suspect it's about 14#. Wolff calls their 14# recoil spring (#47314) the "standard" weight recoil spring for the 4506. I'm not sure I agree.
A factory S&W 4506 (standard power) recoil spring (#201610000) measures in the 17-18# range, for me, & Wolff's 17# 4506 recoil spring (#47317) nets the same force in my testing.

Was that simply the same as the PPC-9 which is very nearly the same gun but with a different finish, in a slightly different caliber?

After I got my 3566 Limited I searched the forum for related info & someone said it used S&W #060480000 recoil spring (14#). I say that's wrong.
My 3566 Limited was unfired & original. The installed (356TSW) recoil spring was longer than a new 5906 recoil spring (#060480000). The 5906 recoil spring measured 4# less force (when installed in the 3566) than the factory 3566 Limited spring in my testing.
Wolff's 15# 4506 recoil spring (#47315) measured the closest to the factory spring, in my testing. (See chart below.)
Once that recoil spring needs replacing I plan on using a S&W factory 4506 recoil spring (#201610000) or Wolff's 17# equivalent spring (#47317) which gives a few pounds extra force for my full power 356TSW handloads.
With my Briley 9x19 barrel installed in the 3566 Limited, which I know you also have one of, I use Wolff's 5906 extra power 16# recoil spring (#47416).
I only handload (+P) & (+P+) 9x19s & this spring works good for them as well as some (low power) target Winchester 115gr FMJ (white box, #Q4172) ammo I bought just to try in it.
