Surely you can play more games, but many top 10 Hall of Fame members, who play full press only, made their points in not that much games. 100-200 (the same as me for. eg.)
Also this is a zero sum game, so it doesn't really matter how much you play, the points available on the site remain the same, so does the average. The flow of points is slower among fullpressers (from the individual player's point of view) but it's the same.
7 gunboaters can play 10 games in the same time while fullpressers play only one, but their total point will be the same after the games. The distribution will have smaller spread though, of course.
Statistically you survive (draw oor win) 50% of your games, so risking 1/7th or more of your points is really not a big risk to take. And there are way too many players who could risk few hundred points.
Also, among gunboaters it was easy to find people to join 1000-2000

bet size games, even though they had about 3-4-5000

only. I joined my first 7000

pot size game with having only 2300

all together. So, what I see is gunboaters are willing to take bigger risks I think. But I don't know why.
