Plot legend
This last data point was again good (S = 0.0030, W = 0.835), and almost aligned with the previous three points. Therefore it seemed appropriate to stick with a straight trend line, defined by least squares on the last four Slumber points: A + B*(d-d0) where d-d0 is the number of days since Apr/03, A = 2670.77, B = 64.48.
The Bitstamp prediction, as usual, is the Huobi prediction divided by the currency conversion factor R, which was assumed to be 6.20 CNY/USD (it was 6.23, 6.20, 6.13 at the last three Slumber Times).
