I'm running a MN, don't have any issues, I think. Getting 33 coins per block now (33%), so I assume that's okay?
Nonsense.
midnightwish what does it mean?
According your calculations should be - 12 miners, 6.9 nodes, 2.10 dev. Why 33?
Because it is 33% that goes to the masternodes. 33% of 100 is 33. The block rewards vary so the net amounts will vary to match.
