Maybe this is a dumb question, but how will we know if you choose not to post a losing bet?  It seems to me that you could win 4 in a row, then loose one, but don't say anything about it, and then win 3 more and claim that all 7 were "in a row" even though there was a loss in the middle.  I'm not accusing you of doing this, I just don't understand how we would know if you did do this.
