Today we had an average 0.0114 / Mh/s.

(131.89 + 35) / 14700 = 0.0114
35 is an approximation of unexchanged addition today.
14700 is an approximation of the average Mh/s for the pool today.

It could be nice to keep track of unexchanged amount at the start of the day, in order to have more accurate stats.
(Starting at 83.5 for tommorow.)
