I am sure that this is a dumb question... but is the VARDIFF correctly weighing the more difficult shares?  It is probably circumstantial, but I increased my hash rate by 50% from yesterday, yet my overall payout was 30% less?

Also, you probably know that DOGE forked and several pools went down.  As a result, difficulty went down with it, which should put it about 1.4-1.5x LTC for profitability right now.  I just didn't know if you wanted to roll that coin into the list of options...

Thanks.
