Now imagine you are doing this every 5 minutes... you won't make much profit.  You can combat this by increasing the profit switching interval to a much higher number.  30 minutes is probably the minimum you should look at.

In my opinion, it's actually better to look at the trends of the coin, rather that what is most popular at that instant.  I would prefer to see AM use a weighted measurement average to determine the most profitable coin.  For instance, if you set the interval to 30 minutes, it should check to see what "place" it's in.  If the coin is in the top spot, it should get a "1".  If it's in second place a "2".  Then average that number with all the other interval checks over say the past week... and the lowest average number is what you should be mining.  That will reduce switching to coins that will not perform well, and will bring more profit.  It takes into effect the time it takes for the pool to accumulate coins, send them to the exchange, and then pay you the spot price in BTC.  I think a weighted average will give you a lot more consistent profit.  I'd love to see this feature Patrike!
