By popular and unpopular demand here is the check on my latest "Chinese Slumber Method" prediction
Prediction posted at: 2014-02-13 04:47 UTC
Prediction valid for: 2014-02-13 19:00--19:59 UTC (04:00 -- 04:59 China time)
Predicted Huobi price: 3970 plus or minus 30 CNY (3940 -- 4000)
Actual Huobi price (L--H): 3856--3896
The prediction is the blue rectangle at extreme right in this chart:
Obviously the prediction was a bit too optimistic.
However, note that the Huobi traders (or robots) again kept trading throughout the night, so the price at 19:00 UTC was not really a "slumber price".
With that caveat, it seems that the last three Slumber Points (three rightmst yellow dots) lie on a relatively straight descending line,
Predicted Bitstamp price: 650 plus or minus 10 USD (640 -- 660)
Actual Bitstamp price (L--H): 611--635
Again the prediction was too optimistic. On the other hand, the Huobi price at that time, divided by the dominant currency factor (R = 6.12 CNY/USD), matched the Bitstamp price quite well.
In the following chart, the red/green strokes are the actual Bitstamp prices, while the yellow dots are the Huobi Slumber Prices (mean prices at 19:00 UTC every day) divided by the appropriate currency factor (R = 6.40 for feb/07 to feb/09, R = 6.12 for all other days):
