question on percentages
quick math here tells me I have been off a little bit using the FitDay Pie charts. example is I am trying to use a 50/30/20 protein/carb/fat ratio and after some time now I typed in some numbers and the math didn't add up. 190 calories at 29/8/5 for this portion showed a 60/17/23 ratio which if using simple math shows that the percentages are not accurate. any thoughts?
