I'm not 100% on ethash, nor am I ever 100% uptime on all rigs/gpus, but if I were I'd be around ~3200-3400 MH/s total.  AMD rigs = ~1100 MH/s stays on ethash (ETH & ETC), ~ 18 kH/s on CNR (Monero).  NVIDIA Rigs I mostly leave on YIMP pools/MPH for BTC payouts, a couple stay on RVN.  I try to put a few rigs on new coins/algs early, but dont really spend a whole lot of time researching them so I dont catch as many of those as I probably should.
