This is very interesting because I've had similar suspicions just recently. I'm going to switch off auto exchange for now and follow this thread I think.
i must say i agree that profit are really to low compared what mutlipool says on average
have 2 computers running on 1 account both does 0.0011-0.0012 and my earning are only 0.00117 to 0.00147 it s only the half where is the other half
maybe he is right they robbing us
I checked my historical pool earnings for Eth vs estimated on whattomine - the numbers are within 10%
50% variance is not uncommon - earnings are PPLNS based on blocks found by the mining pool - MPH is not a PPS (Pay Per Share) like Nicehash. You'll be subject to pool luck.
I'd start mining a different algorithm or coin if pool luck for your miners is 50% - I've even seen changing mining software can get me a different result - for example for lyra2z, ccminer-djm34 reports a hash rate close to the share accept rate on MPH.
it s not just 1 days it s the data from the last 7 days can't be bad luck everyday
for now i disable auto exchange
i remember in the past when i checked it was also in the 10% ranch on my other account, but i can't check now there as i have a lot computers, some coins i don't exchange and the other i exchange to musicoin it s more hard to check
as on this one there are only 2 same computer autoexchange to btc but it s look bad like 40% is wasted
ok so i did the math from 30-03-2018
report earnings was 0.0010 - 0.0012 x2 as there are 2 computers
0.02503630 btg 0.00015780
0.13302335 mona 0.00005988
0.00155978 xmr 0.00003940

0.02636765 zen 0.00006027
T 0,00230548 without the fess and i adjust the price a bit to yesturday
and i got paid 0.00155148
so so much lost in autoexchange ?
i checked for today , the coins are there, so can't be bad luck
