The one thing that is different is the labeling. I found that in my gun , U1 is like IC, U2 like mod and U3 like full.

This isn’t a mystery if you know the bore size.

And labeling on the choke does not always reflect what your actual pattern will be in your gun with your load.
No it doesn't, and my own testing shows that my results don't agree with Muller's idea of what patterns his chokes produce. My gun and loads produce tighter patterns.
It’s those Kent shells you shoot.
I have always thought gun manufacturers should just label a choke with the amount of constriction, like some of the after market choke makers do and forget the labels based on a pattern percentage that is rarely achievable with said choke.

It finally got warm enough for me to get out to the pattern board with the Muller tubes. My testing was very minimal, mostly I just wanted to see that the tubes put the shot where I wanted it to go more than anything else. One shot through each tube with one type of ammo, el cheapo Winchester super target #8 at 25 yards so the results are far from conclusive but generally I think they performed well. The patterns are well spread out with no hot spots and few flyers where they are not supposed to be! Not sure at this point if I'll bother to go back to the board, sometimes it's best to leave this stuff alone!
