"Masternodes: Seniority will get you +3% ROI on your block reward for every 4 months running your MN. For example, after the first 4 months, you will get 25.98 + 3% = 26.77 rewards per block."
How is senority time counted? Is is the time the MN is running? (shown in the tab "time active"). If so, that would mean if i restart a MN, it begins to count from 0 again an you will lose your bonus?
Seniority is counted from the moment you created the tx id for the 100.000 SYS transaction for your MN
So restarting the MN does not affect it
