You have to look at the series (2 games) as a whole.
We do not lose anything unless the game 2 wager loses.
So...the record is based on each series...if it was a winner or a loser.
If game 1 wins...obviously that is a winning series. 1-0
If game 1 loses...it can still be a winning series if game 2 wins with a 2 unit wagers. Still 1-0 for that series.
If game 1 and game 2 loses...we lose that series. 0-1
Think in terms of series...rather than individual games...it's less confusing.
We have 2 games to win one wager in each series match up...and still count the whole thing as a win.
Do it a few times and it all becomes clear...explaining these things in a forum to thousands of people is always tricky.
If they keep winning...trust me...you'll get it.
