I'm not challenging your knowledge at all. I know yours far exceeds mine. Maybe I'm just thinking about this in the wrong context, but do you not think overall network difficulty in needing such a large share to solve a block and the advancement of ASIC chips have made any difference?
Am I wrong that the higher difficulty the larger the share possibility could be?
I guess I'm coming at this from the angle of working on a stratum and it auto adjusting correctly with highest probability to solve a block for each individual specific miner model. + I just wanted other miners opinions.
