Have bolded a few passages. You are dancing between "pure abstract probabilities" and "odds" which are not one and the same.
I'm just using those words, interchangeably, in the context of my OP. Same thing when I use the words "chance" and "probability". It's all in the context of "on-paper... as the league is structured".
I have yet to see from you or anyone such an extensive and exhaustive discourse of this concept being put forth of a "fair team". Having observed and participated in team sports for over 60 years, I have yet to see a satisfactory explanation, definition or criteria of this mythical "fair team" .
I'm not sure where I've used the term "fair", let alone the words "fair team".... without reading back through everything I posted, but I don't think I did. Forgive me if I'm wrong. I spoke about "all things being equal", and very specifically, in terms of the layout/format of the league. I think you're the only person talking about "fair", and then when you do, you're citing factors such as scheduling to evidence unfairness.
I also really don't feel like my OP requires an extensive/exhaustive discourse. I think it's pretty simple.
I'm really not sure what there is to discuss, unless you are suggesting we should put the time/energy in, to further refine the exact values for each season, by examining each team's schedule, and modifying (buffing/nerfing) the probability values on a team-by-team basis. I honestly wouldn't spend my time like that unless I was getting paid to, because it would be a monumental task... and it's not going to affect the numbers any noticeable way, such that the results I posted would differ much. Honestly.
In other words, you're splitting hairs where I already know the results aren't affected by... hairs.
Further to that... everybody here, and everywhere else in the world, already knows that no two teams have ever been matched exactly, or have identical situations beyond the very first decision a team has made.
1967 expansion. Sponsorship era. The expansion teams did deal with the O6 teams but since there were six expansion teams the results tended to wash. 2017 expansion-only one expansion team. Did not have to compete with other expansionteams for the same players.Huge and measurable difference.
This is a perfect example of just how "on paper" I'm talking about. The
very moment the NHL approved both Pittsburgh and Philadelphia for expansions teams... those two teams were "equal"... in that they both had "the exact same odds" of winning the cup.
That's it. Go no further, than that moment. Because nothing more matters. Just the on-paper part. As soon as you introduce a schedule, you're tilting the odds in favour of one team, over the other. But not enough to show any fault in the math of my OP.
