Hmm. It used to work that way -- where task difficulty was a factor, but perhaps they changed it in the most recent stat formula change. Apologies if I gave you the wrong answer there -- I've been around for a loooong time. But for the example you cite, it's 0.5 % --- so 50* 0.005= 0.25, and multiplied by 7 is 1.75, which is the number you're seeing.
