When it comes to balance, keep in mind that immature & unexchanged are just estimates in BTC as their name state. If the market go down, your immature & unexchanged coins worth less.
Yes I know, and that's exactly my point, if the coins had been auto-exchanged like the pool states, then I would have gotten the original amount stated, rather than the decreased amount that happened when the value of the unexchanged coins went down.
I don't think anyone can predict a coins value in advance. If you can then by all means please do.
