i was here on kano.is for two months before i leave it, and now came back again after one month, my question is where is my ramp up period gone?
It is already more than 24hours since i moved here on kano but my shift graph showing avg 0.84Th/s Huh
...
The 'ramp' is a name people use for the effect of PPLNS on Rewards.
The Reward code selects all shares found 5Nd before the block is found.
Since you left (long) before the last 5Nd, you only have your new shares as shown in your graph.
If you click on the "time key" checkbox at the top, you will see the left hand side of the graph is after you quit mining.
The light red area shows the 5Nd before the last block we found about 16 hours ago.
Thus if you've only been mining for 24 hours, then you had only been mining for 8 hours when the block was found.
Alas I guess you also didn't notice that when you left a month ago, your 'ramp' down will have included (very good) Rewards after you left.
Have a read of the Help->Payouts page - though I presume you worked out that when you were here before?
Also, the Shift Graph shows the average over, about, the last few weeks, not just the 5Nd.
Your Reward for 514974 will show what your calculated hash rate was for the block's 5Nd
do i need to start my ramp up period again or what.
Yes coz you 'ramped' all the way down and got those 'ramp' down Rewards also.
I remembered, a guy who was in same situation as i am and he asked you same question about ramped up period, he was completely ramped up like me, he left and came back and you answered him differently by saying he already completed ramp up period and no need to do it again.
