There is no such thing as 101% shdw

12.5% would be 25% blue according to what you have said.
eg. You have 47.26% xp. Yellow displays 47%. Blue would be 72.6%.
eg. You have 81.97% xp. Yellow displays 81%. Blue would be 19.7%
Next question.. could you use some nifty layering/UI skills to draw these two values together and hide/create a new decimal point?
47%--72.6%
=
47- - . 2 6% as a basic idea. Obviously that would look stupid.
