for 24 hour profitability settings, why would you not set it to 1 minute or 5 minutes? It doesn't switch very often anyway. The problem I have with that at least on my system is it will basically just mine bitcore forever.
From my experience you need to be careful when selecting pools for this. AHashpool is most reliable in terms of not experiencing / showing crazy spikes, while zpool and MHP are the worst.
In my experience, ahashpool stats are totally misleding. I deactivated it from my profit switch.
I find all the values shown by AM misleading, they simply have absolutely no relation with the reality. I tried with 3 separate test rigs and with the same settings and same GPUs one shows $100/day and the the other shows that is it making $5/day.
It seems that statistics and profit that is shown are just random numbers.
PATRIKE, can you read it and explain why all profit values from AM are RANDOM NUMBERS ? It changes from one miner to another based on random numbers, nothing that has to do with reality or at least with the values from whattomine.com !!!
the computers you have are not properly configured, by no way once it is properly configured and you eliminate bad pools (eg, MPH skein with frequent spikes) you are going to get erratic difference. Once it's properly configured, expect you are not getting 24h earning fluctuation more than the 24h price swing of BTC itself
