Example: if the 2015-2018 Warriors played the Peak Jordan Bulls teams in seven games series for ten seasons straight, what would be the average series margin in games on vs games lost and in which team's favor?

Warriors 2015-2018 vs 1988-90 Bad Boys?

Warriors 2015-2018 vs best of Bird Celtics?

Warriors 2015-2018 vs best of 90s Bulls teams?

Warriors 2015-2018 vs Showtime Lakers?

2015-2018 Warriors vs West/Baylor/Chamberlain Lakers (compare with no three ball and then with three ball)

Warriors 2015-2018 vs 66-67 Philadelphia 76ers? (compare with no three ball and then with three ball)

Warriors 2015-2018 vs best of Russell Celtics (compare with no three ball and then with three ball)

It will of course depend on how one understands/parses the question.

Based on average play during span, assuming roster strength decided by average RS health (just because then you're dealing with an even and known sample rather than speculating whether someone might be healthy later if the team got eliminated one year). Without looking too deep into league standards and just looking at within era goodness.

Single series are noisy but I think trends would be
Warriors comfortably
Warriors (do we just mean '86 Celts here? Their 9.06 SRS is quite a way ahead of 1980's 7.37)
vs best versions ... coin flip
Warriors (versus many Laker teams comfortably)

With the time gap that far and rule changes that different it's harder to be meaningful guessing how whichever team has to adapt to whatever rules (palming rules unstated here). Even comparing dominance within era ... differences in league size and talent pool require some caveats.

But Warriors were vastly and considerably more dominant than any Baylor, West, Chamberlain Laker team (unless you want to say Baylor technically was on the 71-72 overall roster, did get a ring so ...).
