(16-03 / 20.00h)
I believe we have had today a day tempo of 1:2 (1 h. jangraph = 2 h. todaygraph)
Which means as prognosis:
beginning down 6 hours later from now = 12 hours = 08.00 h. saturday.
lowest point 14 hours later from now = 28 hours = 00.00 h. sat-sunnight.
latest top from 37 hours from now = 72 hours = 20.00 h. monday
But it wouldn't surprise me if it goes faster and the downtrend (beginnig of the tail) wil start mondaymorning or -midday!
