Looks awesome ! I will talk about that to my miner friends ! However I find that your default values are a bit low, especially considering the rig reboot time. Rebooting every six minutes is, except in case you have a very unstable miner, not necessary. The miner reboot put by default at two minutes is maybe a bit low, don't you think ? With the DAG loading time, you will end up losing a lot on profitability I think.
It only reboots the application/machine if it detects a crash (GPU utilization drops below threshold for too long). Ethminer takes less than a minute to start up (including DAG loading) on my Celeron, so I actually thought I might have set my values a bit HIGH because if it reboots the app it has another four minutes to start up before the entire machine gets rebooted. Feel free to adjust as needed!
