It would be nice if the logs indicated a "devfee" block of time so it was easy to know or see when it was working for the dev instead of just randomly submitting dev shares throughout the normal shares.
Will it change anything? Just count your own profits, ignore dev's profits. He wrote the miner => he is smart enough to hide from you shares that he doesn't want you to see. You can probably do a MITM on your rig to figure out whether info in the miner's console represent reality (but something tells me that's beyond your abilities)
The promise I have is that no matter what time of block I pick in my logs (2 hours, 4 hours or 24 hours) it seems to always come out around the same high % over 2% so that's why I am trying to understand how he is doing the dev shares.
Once again, amount of shares means nothing as they are of different difficulty.
Educate yourself before arguing.
