Mini report for the past 12 hours. The average speed according to the statistics of flaypool was 1540 and it was 1580. Ie, the gain is 2.5%. It seems to be not bad. But considering 2% devfee there is a gain of 0.5%.
Everything that is shown by the pool belongs to you - you don't have to subtract the dev fee from it, so if I understand you correctly your earnings increased by 2.5%.
For people that are doing tests:
The share rate is subjected to probability, this is why it's jumping all the time on the pool side. If you want to get robust numbers run it for about 24h, the longer it runs the more accurate to pool is able to estimate your solution rate, be aware some pools might report wrong numbers.
My numbers are exact it was tested by people that are using the linux version , however it's ofc natural for you to check this.
