The exponential decay function was a killer making the first 2/3 of that round worthless to me because I missed the last 1/3. On the next round, missing the first 1/3 did not seem to cost me anything in payout. Makes me think I could have missed the first 2/3 of that round and still received roughly the same payout.
The exponential decay function is a hard master, punishing those who miss the end of a round and rewarding of those who work the end of a round.
Yes, that's why it was implemented - (IF) you are a pool hopper you loose almost immediately.
It's not 1/3 or 2/3 of the round - it's a matter of ~20-30 min, so for a 11h round you may miss 10:30 of it and get the full reward (joining at the end) or miss the last 6% of it and loose all the reward you had
