I have an 18 year old and 19 year old, both same level of FT. The 18y is listed above when ordered by FT.
The 18y popped 1 week ago, the 19y popped 6 weeks ago. Therefore I would think it's very likely (certain?) the 19y has a higher sub-level.
That is pretty definitive, unfortunately.
it's sorted by position first
I have 6 players that have the same skill level and they are not ordered by nominal position (PG, PG, SG, PF, SG, PG). However there might be something there bound to the salary formulas. I.e. they might be ordered by their salary
in the PG formula. That would be consistent with my data sample...
BBB: 2 (S37 S38); Top tier: 7 (S35 S36 S37 S38 S39 S41 S63); Cup: 9 (S25 S35 S36 S37 S38 S39 S40 S41 S61)
