This is comparing type advantage against all other Pokemon, which isn't representative of actual strength, because most other Pokemon are not viable competitively. What actually matters is type advantage against only the Pokemon with good stats and abilities. Here's some recent usage stats of top ranking players using the strongest available Pokemon (although lightly restricted by rules designed to prevent excessively boring or luck-dependent matches): https://www.smogon.com/stats/2018-02/gen7ubers-1760.txt https://www.smogon.com/stats/2018-02/gen7ubers-1760.txt Ice and electric are very poorly represented. It would be interesting to re-run the algorithm on only the top n from this ranking.
