As soon as the prize money for pinball is comparable to any of the above I'm sure attendances will sky rocket . All of those are professional sports with 100s of 1000s of competitors doing it full time - this is a hobby realistically, with significantly less competitors.Eg golf, tennis, darts, snooker all.based on points or.prize money earned as far as I'm aware so all encourage you to enter as many events as possible
Chess ranks head to head performances, and also values who the player beaten is. That's similar to how the IFPA ratings are currently calculated I think - a Glicko based system.
Head to head results are used in the vast majority of team sports as leagues are used to evaluate best teams, ranking system for international teams use head to head results and all kinds of other formula applied. There's no reason why head to head results can't be the basis of a ranking system for pinball. Each team is counted as an 'individual'.
