How about polling the masternodes to see what the general consensus is for a percentage and wait time?
i suggested a similar proposal when someone was suggesting 50% +1.
after doing more research i think the 50% +1 is too much but it sounds good on paper. i just like the idea of a majority plus one but i don't think that would work due to low participation rates.
someone suggested a sliding upward scale depending on how large the amount was. that seems like a good idea but may not be easy to do and would not be a priority for me. i want all hands on deck coding evolution and everything else can wait imo.
72 hours and 20% sounds good enough for now.
