Nice work. On nicehash, I'm assuming that's using multi-algo pay rates? How closely does it resemble advertised rates would you say?
No, it's showing algos separately, Scrypt, X11, X13 (note that the latter two are multiplied by certain factor to align with Scrypt).
I would say it's within 10% most of the time. My numbers are generally a bit lower, because advertised rates are more of an "ideal" scenario. Actual payouts are affected by latencies, rejects, DDOS, etc.
