Hi,
dont worry, rig is hashing stable all the time. If you see lower hashrate, than its because of wrong diff or pool thing
SedRig01 is hashing on 4,4 MH/s and SedRig02 on 1,8 MH/s (but you are paying just for 1,75 MH/s). With good settings you can see these speeds even on the pool like I do on for example clevermining ;-)
