Alternate to proportional need not be non-proportional
Maybe leave things just as they are ...BUT... report the Round.... .Shares.....Difficulty.....Duration.....Hashrate info from 24 hours ago
Alternatively
report total shares so far this week and make the distribution at week end when all the round info could be published too
Just thinking aloud here and wondering if all pool's reports are similar just because it started that way and became the norm? sort of making everyone Hashing lemmings
