"I tested playing double or nothings for a while but found them unprofitable. Too little profit for the time spent (ie an hour and half to not even double your money). I think they only engross Pokerstars rake collection, since they take 1/2 or 1/3 of your profit on most sessions. I think normal SNG or MTT or cash tables are way more profitable. Just my experience, as in everything I'm sure there are players whose playing styles might find these most profitable. "
As I said, it needs different playstyle, different skills. However, 59-60% won tournaments can be done if you make good decisions. That means $70-$80 profit/100 DoN. (please note that I'm talking about $5 turbo DoNs, Ive seen a few graphs on people who have played a lot of those. Higher the level, lesser the winning %)
If you can play 6 DoNs an hour (which is absolutely doable if you play only 4 tables at once and not in "blocks", so if one ends you start another one right away) then lets say it takes 16-17 hours to play 100 DoNs. Thats between 4.1 and 5 $/h.
And that is done playing 4 tables only! Even the most beginner player can play 4 DoNs! If you find it a little bit harder but want to 6-table, it makes it more easy to start 3, then start another 3 in 15 minutes. It makes it less likely to reach the bubble on too many tables at once.
Also, the longer session you play the better your $/h is, since it is possible (actually, likely) that in the end of your session you play 1 or only 2 tables at once because the other ones have already ended. The longer the session is, the less downtime you get like this.
All in all, lets say one isn't perfect in DoNs and can only play 4 tables at once and makes approx $4/hour. I don't think that anyone with a $200-$300 bankroll should complain about such winnings, but I might be wrong. That means you raise your bankroll by 1-2% per hour, I think thats good. Might not be great, but hey - why not try maximizing the profits with other games after you have built up a solid bankroll "the easy way". (at least its better than what the job paid me last summer
well, its true that I can't do this 12h a day :P)
