You must mine for at least a week with 2 different rigs of equal hashrate at both pool at the same time to have a valid measurement.
Ok, problem solved. I changed pool after 24h mining. And after 6-8h my balance increases to 0.35 XMR.
Pool just have big delay to confurm blocks.
day and half, I earned less than expected...
Which pool you are using now, I don't like this pool
You cannot expect to earn what is written on a calculator : this is impossible. It doesn't matter which pool you chose, you cannot earn an estimate because it is an estimate, not a prediction.
In mining it is always less because of the rapid increase in difficulty, the great variance and connection problems.
