In this case, the rankings actually do change although not by much. Steel/Flying beats out Steel/Fairy as the best type combo and Steel/Dragon and Steel/Ghost trade places, but the top 5 are otherwise the same. The bottom 5 are identical in both cases.
The type combos with the biggest changes were Rock/Steel, Fire/Steel, Fire/Rock, and Electric/Steel which were all rated slightly better in the higher order analysis.
