Going numerically through the Kinnikuman/MUSCLE Parts, the first super rare comes to us in Part 13. Part 13 is comprised of two trees and has one super rare sculpt.

Fortunately, or perhaps unfortunately, determining to which of the two trees this super rare belongs seems to be a no brainer for two reasons. Lets first take a look at the graphical breakdown of Part 13. (Each of the trees is labeled with (1) which part it belongs to, (2) which tree within the part it is, (3) and which tree number it is overall.)
I hypothesize that Kinnikuman #191 belongs to Part 13, Tree 2. The reasons being that (1) Tree 2 has one less MUSCLE sculpt than Tree1 and Kinnikuman #191 fills in nicely, and (2) the SR MUSCLE that Arforbes has is Red and Tree 1 doesn't appear to come in Red, while Tree 2 conveniently does. (In the above graphics, it is represented by the Gray boxes.)
Part 15
The next super rares come to us via Part 15. Part 15 is comprised of two trees and has two super rare sculpts.
(1) Kin #222 (Dark Emperor/DE)
(2) Kin #223 (Drunken Master/DM)

From here on out, the hypothesizing deteriorates into a genuine crap shoot.
In this case, the Gray boxes represent 3 Kinnikuman sculpts that were not made into MUSCLE sculpts. However, as we know, 2 of these 3 sculpts have mysteriously been found in MUSCLE plastic. Guessing which 2 of the 3 Gray boxes above those two sculpts happen to be is, well, anyone's guess.
Part 21
The last MUSCLE Part that brings us super rares is is also the last MUSCLE Part period, Part 21. Part 21 also consists of 2 trees (Woohoo, a pattern!) and has 3 super rare sculpts and 1 that has only been found in Flesh.
(1) Kin #292 (Satan Cross/SC)
(2) Kin #304 (Dr. Bombay)
(3) Kin #305 (Spinning Head Ashuraman/SHA)
(4) Kin #306 (Black Hole Sunshine/BHS)
As you can see, this Part has 6 Gray boxes which represent 6 Kin sculpts that were not made into MUSCLE, but collectors have mysteriously found 4 of these 6 sculpts in MUSCLE plastic. Once again, however, it is anyones guess which of the 6 Gray boxes are the 4 SRs. An additional complication is that there is no way to evenly distribute the gray boxes between the two trees because there is an uneven number of sculpts/boxes overall.
Note: The Kinnikuman Numbers assigned to each sculpt were taken from Jkaris' Kinnikuman Index. I'm not sure how he arrived at the number system, but perhaps it can be used to place the sculpts correctly on the trees?
If so, that'd be pretty #%@& cool.
