Hmm, actually not sure why no one noticed this on the graph posted above a number of days ago from minergain,
but the 12 months going from Feb this year back to March last year has us higher than both slush and viabtc ...

The reason the 13 months including Feb last year was lower (but not much lower) was coz Feb last year was the lowest luck % month on the pool over all time.
So including that as the start point will push the total down.

... and FYI Mar last year isn't the highest, the 2 highest are Nov 2014 and Apr 2017
