Thanks 1819.
I was thinking of commenting on this post when I saw it, but knew you would come along and clear things up for us...again.
I always think by changing the coin amounts the machine will hit better, and sometimes it does, but that may be because it's just hitting at the time of my coin amount change.
So, the casino secret about the "timeframe", is that from the time they place it on the floor until it's taken off and replaced?
