To see the data are good by half, but they have many currencies. They usually fail in the basic data, difficulty, reward, hashnet. In those 3 CTM data is harmful, but it is good in prices and exchanges. Acquire the prices faster.

The only advice I can give you is to do benchamrk. I mean a coin, with a pool, 2 -4 hours of testing. Take several samples of the currencies that average AM, I do it with scheduled captures. And after 2 hours you compare the obtained, with the estimated that would gain in 2 hours (24 hours divided by 12 = 2 hours) and with these two data and a rule of 3, you get the profit. I benchmark all currencies, regardless of the provider. In that I have seen that GRIN29 with CTM the profit should be 2.1, 210% more than what it predicts, while CC is 0.95.

It is a complaint that I also have, and the only solution is to test the coins to find out their real profit.
