Interesting, thanks for the response.
That means there's a matching jump forwards a while ago, and it seems to be here, mid December.
The counts didn't line up for a while, but they do now, so that's good.
512,305
We jumped back by 1000 counts a while back.
I don't know if we a) continue from 513023,
b) Reverse the 1000 jump, and count from 513,306
or c) ignore it entirely.
