Ah, didn't notice the hover numbers. Very nice.
I can see how you consider some level of precision as noise for high salaries but I think it makes a difference for a rookie. Plus, the fact it is innacurate (mainly because of sublevels and a little bit because of the formula) doesn't mean, in my opinion, that rounding it to the thousands will make it less noisy or more accurate ;)
But, I'll give you that: since you use 2 different formulas and probably calculate the average, then rounding does seem to make a bit more sense.
