Why does bitminter report 48 GH/s and BFGMiner 56 GH/s

What's up with that?

What's with the dual BTC MNC mining?  Does doing that hurt your bitcoin production?  If so is there a way to disable it?  Should I?

Is it the same issue as the discrepancy between bitminter and BFGMiner for speed or something else?  I tend to think it doesn't have to do with it because bitminter gives only one speed but two separate figures for accepted work units (or whatever they are).

Nothing to worry about. Hashrate on BM is only an estimate. Namecoin is an extra. You can sell them for Bitcoin.

If you hold your mouse pointer over the column headings you will get a tooltip explaining them. The hashrate is just an estimate. Accepted infinity means all accepted proofs of work for all time. Accepted round means how many accepted proofs of work you got this round.

The namecoins are created using bitcoin hashes. This is allowed by the Namecoin system as it supports merged mining.

If you don't want those free coins that don't slow down your Bitcoin mining at all, then you can set Namecoin donation to 100%
