To highlight the formula I put it in white text. But you're propably right, that alone might not be enough to highlight it. Maybe with increased text size?

On my calculation, the formula I put is correct. Here I equated the original with mine:

Here is the original formula equated with my version of it: http://www.wolframalpha.com/input/?i=b+%2B+g%C2%B7(n+-+1)%C2%B7(0.685+%2B+0.0175%C2%B7n)+%3D+b+%2B+g%C2%B7(7%2F400%C2%B7(n%5E2+-+1)+%2B+267%2F400%C2%B7(n+-+1))

You're right, you first get when expanding the formula b + g·(n - 1)·(0.6675 + 0.0175·(n+1)) But the 0.0175(n+1) = 0.0175 + 0.0175n, and as such can be further simplified, with final result being

b + g·(n - 1)·(0.685 + 0.0175·n)

That'd be

Hello Sanitiy, Alright, you are right on this one, but still, ask an administrator about this change because it is really significant.

In terms of clarity, I still think the old formula does a better job because both of the $$ n^2-1 $$ and $$ n-1 $$ share the same denominator. That's just me, but I feel like it's more comprehensible in terms of how the formula is formulated.
