Okay so I'm on v0.9.2.49.06.XCurrency-REV2 running xminer.
My question is about the seemingly random way xminer works.

1. Now my weight is 7504, but every time I turn it on it's different (although the amount in the wallet is the same).  What are factors that impact that?

2. Time to earn reward also gyrates wildly. Sometime it's 17 hours, then 20, now 21. Why?

3. It seems (from 2, above) that xminer isn't useful (i.e. is useless) if you need - and I do - to show down your PC once or twice a day. Is this true?
