on this miner hash is the highest!
commission developers really 1%? who checked?
Indeed it's the highest, sparkpool:

4x1080ti+4xVega64, both running AceMiner.
Interesting question on the other hand, as it is also my impression that miner fees are more than claimed.
I wonder how often and for how long, makes up for the 1% stated.
I doubt it's the fastest miner with claimed change of 2% down to 1% fee only. You could reach Your second number (24h) only with 4x1080ti if really fastest Grin miner used.
