Fun mining mathematics in the afternoon,
I have noticed that the mining hash rate is somewhat sinusoidal in nature (a noisy one at that)
http://www.coinwarz.com/network-hashrate-charts/dash-network-hashrate-chartSo I decided to work out the period, frequency and amplitude.
Knowing these constants, it is possible to predict the next best and most profitable time to mine (or not!) and see the general 'mood' of the network.
The last 4 peak to peak waveforms and calculate the median hash baseline (almost at a new peak which is not included)
Average of last 4 peaks = 85.8 gigahash
Average of last 4 troughs = 58.7 gigahash
Result: Median baseline = 71.26 gigahash
Amplitude (from baseline) = 13.26 gigahash
Peak to peak period and frequency:Times between last four peak to peaks waveforms (hrs) = 14 + 25 + 31 + 18 = 88 hrs
Average peak to peak time(period)= 22 hours
Frequency = 1.1 hashing cycles per day
Predictions:Last trough was today at 02:00 GMT so the next one will be 22 hours after at 00:00 GMT midnight tonight (on average)
Next peak will be at 11:00 GMT tomorrow.
ConclusionsFor most profit per kilowatt hour mining.
Switch miner on at 20:00 GMT tonight and turn it off at 04:00 GMT
Make sure miner is turned off by 09:00 GMT tomorrow for over 4 hours.
SpeculationsOddly, the hash period is slightly less than 1 day length at 22 hours, almost as if one part of the world is trying to beat another part to hash first, and they keep over taking each other by shortening and lenthening and then it resets and repeats again.
Edit: So our hashing wash cycle is 1.1 cycles per day, and a woman is 1 cycle per month
