I went back to the calculater and took the last numbers for what they were, I get it though if the gear box acts like a 18/39 then having 18 at both the other locations would make it 50/50 since the front is 18/39.


Anyway,
I entered these numbers into the calculater:
18:18 16:37

and I got this...
CS Ratio: 0.2
CS Percentage: -80
CS FDR: 0.2

Could anyone explain it?
Also did I enter the numbers in the correct order when I submitted them?

Thanks!
