Your shift graph average line change, each shift, will be affected by the point that moves off the left, vs the point added on the right.
However, on a diff change, the length of the 5Nd will also change, in this case it got a little longer due to the diff drop (-0.63%) so that can affect it also of course, but only when the diff changes.
understood - the point dropping off the left is nearly 20 TH lower than the one adding to the right. I would just love to be fully ramped up, its been since Feb and I am still 15 TH from fully ramped up, when yesterday i was only 13 TH from it, so from my perspective, I am moving backwards not forwards.
Yeah that's probably the 0.63% and a little variance.
The extra 0.63%will add back a few of the older shifts into your average.
The above is probably the cause, however, the graph seems to be running off the left end since the 5Nd is getting bigger, so I'm not 100% sure it's correct.
The average number shown there is calculated when it draws the graph, so it may also be a little off due to the large number of shifts now making 5Nd running off the left ...
I've just made the graph a little wider - see if that made any difference.
