The point is to guess almost exactly the forecast for receive a decent reward.. if not, probably you will receive a big 0 reward.. Just look at your account.. we did how many forecast? like 40, 50 in total? We already receive less than 10 reward.. and personally i just see that 80% of them are zero.
If they want more forecaster, they need to change the algorithm again.. and more important, they really need to pay something cause we are waiting since 1 year...
