Ski:IQ based on weighted average of difficulty ratings

I think your Ski:IQ rating should be a weighted average of your max IQ for each level of difficulty.

So your IQ on a double black means more than on a single black, which means more than on a blue, etc.

My resort leaderboard has a bunch of people with high max IQs, but on 8 turn segments on blues, and looking at blacks and double blacks, they fall way down the rankings.

I think a 155 IQ on a black is more impressive and probably more indicative of a better skier than a 160 on a blue.
