Okay, comparison #3 started about 20 minutes ago concurrently mining ZEC on Flypool using a fixed difficulty of 10000 (by using the switch "-p 10000").

If you like watching paint dry then you will surely love to check on the status of the miners:

bminer: https://zcash.flypool.org/miners/t1dU7Gve41A3b4mxL7a3oVAnBLsF9kMgDgA

I created these two addresses just for this test so they are starting from 0.
