I am using the default settings... Switching interval is 30 minutes... Threshold is unchecked.
However an update:
Suddenly my auto-exchange coin target (ethereum) balance jumped up and now my total looks more correct for the 24 hour period ($~7.00).

They must be using some kind of server farm (NoSQL DB setup perhaps) where depending on which server you are hitting at the time, you see different totals. Then at some point they must consolidate. Really wish they would improve the UI however.
at MPH it's hard to consolidate earnings especially when using the AutoExchange feature, the constant shuffling funds to and fro, the delays + exchange wallet maintenance cause lots of ppl to freak out. Glad you are seeing consistent stats now
