Even a single 350 kH/s Gridseed will submit one share per 24 seconds on average with difficulty 128. This is more than enough.

Thanks for adding this feature Terk!

I've got mostly GridSeed 5 chips, and when peeking in on their performance on CM I noticed that often there would be a few struggling a bit, with several hundred seconds between shares submitted. My guess is that this was because the difficulty assigned by the pool was based on the total MH/s visible through the single IP address of the rig, without visibility into the individual mining units.

For now I've set my rig difficulty to 128. This seems to make the GridSeeds "happier", with more frequent submits. I've used 256 on other pools and have had similar results.

Experimentation aside, do you have a specific difficulty recommendation for GridSeed 5 chip based rigs?

I realize that this has nothing to do with overall profitability, it just affects variability. Although I suspect that in extreme cases it could be that some miner software might inadvertently reset a GridSeed that goes away for too long laboring under high difficulty. Since that could result in lost work, it makes sense to try to "right size" the difficulty for these devices.

Thanks in advance for any specific difficulty recommendations for GridSeeds.
