[QUOTE=bobatl;31299445]I get it now, I see why the Unofficial calculator is wrong now. Just a quick clarification on your post in case someone else has this same confusion. there's a typo - I know you mean 1.2 not 2.2.
So in my case:
19568 * .25 = 4892
4892 * 120% (or 1.2) = 5870.4
4892 + 5870 = 10,762 RDMs
Definitely not a typo. It's just a bit more streamlined version of the exact math you did above. Let's just think of as a factoring problem.
Your math was 4892 + 5870 = 10762
Basically 4892 + 4892*1.2 = 10762
4892(1 + 1.2) = 10762
4892*(2.2) = 10762
