Hi, taking your case as an example of the formula i just mention few posts below your post.
Assuming you have fully ramped up and you have 37THs ave.
Formula =
(N/PN)=S
R*S = Your BTC received
(Legend)
MY HASHRATE = N
POOL HASHRATE = PN
MY number of SHARE = S
BLOCK REWARD = R
------
(N/PN)=S
37,000 / 46,880,000 = 0.00078925 Share/Contribution from the total pool power
Block reward (R) = 12.40460222
R*S = Your BTC received
12.40460222 * 0.00078925 = 0.00979032 BTC on this block IF you were already fully ramped up.
Assuming we find 10 blocks of thesame size you'll get 0.096892 BTC in 30 days which should be way
more better than 0.003094 a day * 30 = 0.09282 BTC
Hope this helps. As many long time miners here say, be patient and it will pay off!
