You've never read this?
There are minimum 40-credit cashouts collected into the "soft profit" pool as I go thru (up & down, depending on the level-recoveries) the denominations. In order for me to stop playing, that pool has to total at least $2500 when I return down to the dollar level to re-start. I also stop playing if I finish playing thru all the levels without getting the required $2500 ahead. There can be thousands or even (much less frequently) tens of thousands of dollars in the soft profit pool by then.
Few if any people understand how this works, which is why I tried so hard to get Frank in front of the machines with me. And just in case you see another feeble attempt, plan on arci coming on and making up his own spin on the strategy because he doesn't know it either.
