140mm CZ75 mags... 18rd w/short CZC base pad... capacity?

I've got a few SP-01 mags with the CZC short basepads, and CZC followers with 10 coil springs. I can't get past 22rds in any of them. I've seen posts saying 23 or even 24 with "some tinkering," but I've got no idea what "tinkering" to do. Any suggestions?

Very strange, are they all the same?

Yep, I have 3 mags set up this way, all easily fit 22, none can fit 23.

Could they be using the mec gar 19 rounders and adding the base pad?

As far as I know, the mecgar 19's with the short base pads are longer than 140mm.

how much room in the mag between round 22 and trying to get the 23rd in there?

is the spring 10 coils? or perhaps is there 11?

If I use an UpLula, I can get a 23rd in there now, denting the case of the 22nd round and nicking the rim of the 23rd with the feed lips in the process, but then it's near impossible to seat in the pistol, and the magazine bulges and binds in the frame right at the spot where the 5rd witness hole is. Maybe this is a case of "yep, that's how 23rds feels in these mags," and I'm just overanalyzing, but I figured it was better to ask.

The springs were cut down from 13s by a CZC tech for me since you guys were/are sold out of the 10s. They look just like the picture of the 10 coil springs from your site, though. Here's a pic:
