You're absolutely right! these are the python times:

* less than 5 hours (easy) => 34 minutes avg * less than 24 hours (medium) => 100 minutes avg

So Python is deliberately left out?

No, just forgot about it, I like Python pretty much.

Well, the OP has picked a completely arbitrary cutoff time, thus making any numbers obtained virtually meaningless. As suggested elsewhere, use the median and quartile ranges for non-normal distributions.

I doubt it's a troll, I'm sure it's well intentioned.
