and?
that minimum 25nm was done in laboratory settings (ur ball test on pip isnt the same, isnt correct)
u can say u know how ck531a behave and opponent can say i use different strokes so i get different results....

i had the same problem, many of my opponents were using dawei 388d-1 large version which is illegal
i spoke with head coach our state/provincial and he told me that all referee are doing the same:
-they check logo on rubber/pip and compare it to approved list on ittf site
-they check if rubber/pip have ittf logo stamp on rubber/pip
-they check if pip have all pips
-they check if rubber thickness isnt above 4mm

so referees allows to play with dawei 388D-1 large version even if all players complain

388D-1 usually isn't friction-less and they're about as illegal as those different CJ8000 ABC sheets, albeit on pips-out it is way more obvious. Referees here are more sensible on illegal frictionless pips and especially the CK531A is well-known to be available in legal and illegal versions, they take complains quite seriously; in comparison they're quite tolerant on services which have to be very wrong before someone makes a claim.
The point with special CK531A is that it's a modified, cooked, pimple which makes it absolutely illegal, unlike the Alligator Soft or those banned Dr. Neubauer pips.

Add: I consider those 388D-1 'long' versions from ttnpp illegal as well, they're cooked and modified afterwards for sure. I also would protest against the pips from that push-blocker Marcin. So, I'll try to have standard CK531A and 388D-1 at hand when protesting.

I think some the variation may simply be quality control. A lot of Chinese manufacturer don't have a dedicated factory, but make their equipment in multiple factories. No doubt some of it may be illegal (the cheaper the higher the chance), but (as some have said already) unless a referee has calibrated measuring equipment, they can't really make that decision, unless the changed properties are obvious.
