I've played some DoN's with him when I was clearing the latest reload bonus. He was sitting at every table I was playing. I guess it's official now!
We Germans are the sickest grinder ever
First Boku then this guy.
I don't see it as critical as you guys do. I know someone that is playing 40+ tables at a time and making a solid profit of 7-8%. Multitabling DoN's is a lot easier than playing MTT S&G's like Boku does. You never get down to less than 6 players. After you getting used to it a good move based on position, holding, cipcount, etc... doesn't take longer than 1-2 seconds. You need 274 DoN's a day so achieve SN. If you are playing 40+ tables that's about 3 hours/day. So you don't need to play all day and all night long.
And if he played a lot during the year why shouldn't he go for Supernova if he has a reasonable chance. I read that SN is about 28% rakeback. So making SN is almost twice as the winnings he had so far.
