is there any easier way to calculator how much btc I am getting if I am mining trademybit?

I don't know if it is correct. According to TMB, x11 is scrypt * 2.9. is that correct?

for example, yesterday is 0.003 Mh/s/Day/BTC ( scrypt price)

if I want x11, I have to do this:

0.003*2.9=0.0087 for x11

is that correct?
