I'm done with Altpocket for a while.
Despite having deleted all my non-bittrex investments, I apparently still have a profit (quick math, I don't). I've resat cache, had to delete investments that I've sold which were still shown as being hold (literally just imported the fullOrders from Bittrex 10 minutes ago and still the numbers are wrong)
Calculation in general are completely off and the new /my page doesn't seem to do a better job (I know it's beta)
After having moved 80% of my funds to another exchange, my total portfolio value has decreased by ~USD 20K compared to the numbers Altpocket gave me.
I'll be back in a couple of months and see what's up, but for now, check your numbers.
