Hiya Fellas,
The PSI is compared to a golf handicap simply for the fact that is a more conclusive way to rate play, like a handicap is, not because lower is better. Actually, with the PSI, you want it to be higher. Just for basics on the PSI, as we can't reveal the entire formula.
These are a few examples of things that are better for your PSI score:
It's better to finish 5th out of 100 players than it is to finish 1st out of 15. Finishing 5th out of 100 players in a Tier 1 Event is better than finishing in the same spot with the same number of players in a Tier 3 Event.
The primary catalysts for the PSI score are number of players, buy-in, and finish position. So the best way to increase your PSI would be to finish 1st in a Tier 1 Event against a ton of players. The most destructive thing for your PSI would be to finish last in a Tier 3 against only a few players. Obviously, the more events you play in, the smaller the moves in your PSI score will be, hence the entire purpose of the score itself which is to truly gauge how you rate as a player. At some point in the future, players will be asking each other, "What's your PSI?" When you answer, "92.33," you'll hear a chorus of oohs and ahhs (that score would be very high and would mean you had consistently finished very well in many tournaments, with several being Tier 1 and 2 Events).
Once you've played in enough events that your PSI doesn't change dramatically with every finish, then the point is to continually increase the quality of your play and gradually move your PSI score upward. After all, that's how pros become pros at anything, by constantly honing their skills through constant practice.
Hope that all helps a bit...best of luck at the tables.
