Why are +30 and -30 even the options? That makes no sense. It’s not like 0 is some perfect equilibrium of human comfort. Nor is it the most common average temperature in Calgary.
We should be comparing temps that occur with the same frequency. And we should also compare when they happen. Like it’s totally different for the low to be -30 at 3am than it is for it to be +30 from 11am to 5pm.
Comparing -30 to +30 as a binary choice is nonsensical.
