It's intended for a macro to be worse than do it yourself for things like this.
Actuualy I think it serves an indirect purpose tot hat end. When i was testing my MP macro I noticed that Thunder III was skipped because I was I was still casting Blizzard II. I "fixed it by adjusting the /wait time by a few decimals. But if the wait times being rounded is true, then I suspect its to give the illusion of faster queves.

Still I will make my MP macro, but I don't think I'll be using it except for rare situations (and odds are that those will include slow or slowing down DPS anyway.)
