For me that's #2 behind MMA vs DRG in Blizzard Cup.

I have heard several casters (specifically most frequently Tasteless and Artosis) constantly say that you shouldn't do math on stream. However, you will regularly say something like "we have a 37 supply difference here" if it is 145 vs 108. What makes you confident enough to do this on stream (and constantly be correct)?
