I did some tests with antminepool, 30500MH/s (24 hours of stable mining) , I did receive 145 XVG , whattomine says it should be 162. Seems orphans.
Come on, you are complaining for something so close, If the difference was 30% then yes but your case is only 10%.
I guess a stable xvg pool is needed.
If losing 10% of your earnings is not a big deal for you feel free to share 5% here 0xb44c78CFC669a3EEE0338A4F46Ab9D12caD2df51
but you are right about the pool
