100% or 110%

What part of 110% of usual do you not understand? Most people to not work at their limits under nominal conditions, probably more like 85% of possible. So if you give 110% of usual, you're giving 110% of 85%, or 1.10*.85=.935

I don't think that is what he is referring to anyway...

I say 110% so that people know I am trying to exceed my maximum output. It doesn't make logical sense, but you get the point. And if you don't, I pity you. True pity.

Pity.
