I seriously doubt the Pinburgh rules intend to reward poor pinball play at any point.
Since everyone is not encouraged to game the system like this, I would disagree that the portion of players exploiting this fact should be perceived to be skillfully executing tournament strategy. They are taking advantage of the majority (I hope), who are trying to play well at all times. Doing otherwise is disrespectful to fellow players and the "spirit" of the tournament format.
I could be totally wrong, of course. Doug and Bowen might fully expect everyone tank games as part of "macro" tournament strategy. Fine by me if they do. If so, I'd like to know so I can start having the same advantage without feeling like a weasel, instead of getting ripped off for my good play by those that already are.
Like has already been said, it's going to happen anyways if the rules allow for it. I'd just hate to see that become the standard approach for everybody.
