I did not say that I opposed Singer's advice to quit when you hit a win goal? I said it wasn't logical.
Saying that something is not logical, and saying that you oppose it are two totally different things. I met a girl I really liked last week that's not the least bit logical. I have no intention of opposing her, unless it is perpendicular opposition, if you know what I mean? Quitting when you are ahead is perfectly fine in the context of the Singer system. But let's not muddy the waters with logic.
I am not against the practice of quitting ahead for the day for recreational players. Even if they aren't really ahead, and they aren't really quiting. Hay it's a fantasy anyway, might as well enjoy it. I am only against the practice for contrived reasons. In other words, you have my blessing to do as you please, as long as YOU are clear that it is an emotional decision with no mathematical precedent. It's the confabulated justifications that get up my skirt, as they are indicative of risk factors for problem gambling. If you have any doubt of this fact please read the book Best Possible Odds by Dr. William McCown.
