Not sure using percentage as a methodology to separate teams when draws are uniquely uneven in terms of Premiership sides from year to year and then from era to era, not to mention navigating the modern challenges of travel or relative strength of opposition, is the way to go.
Good on you for having a crack but where you lost me was ranking Richmond 2017 at 83 and Richmond 2019 at 86 when I think every Richmond supporter would say the 2019 side were stronger and overall a better side.
By way of quantifying that, 2019 Richmond finished equal top on points (3rd on percentage) and in terms of finals went to the Gabba and won away by 47 points, beat the top of the ladder Cats in a closely fought prelim and then destroyed GWS who had upset 4th placed Collingwood.
Richmond in 2017 won a game less finishing outright 3rd, despite having a slightly superior percentage to the 2019 team would have benefited from their draw given 2016 they finished outside the 8, won through their finals comfortably by 9 and 6 goal margins at home and then cleaned up the Crows by 48 points, but ostensibly beat two interstate sides on their home deck.
One of those sides was pretty clearly the best team all year (and had arguably been the best team in 2018 when they lost the prelim) while the other was very much viewed as a significant underdog and the result of the grand final an upset. Your numbers don't seem to reflect that.
