Dude, just get TO and that's like 50% of everything. The other 50% is organization, contacting people, making sure your setups are there, promoting the **** out of it, and just trying to guarantee to the fullest degree that the people you'll be serving are gonna have a good time.
Also the way those PRs work is they just take the raw data from tourney results from all over and try to rank players according to the rankings. Each place awards a certain number of points which fluctuates according to the number of people in that tourney.
But like the problem with that is that there are some big tourneys that are noticeably easier than smaller ones. Also if certain players don't participate as much, they could be ranked lower than scrubbier players who consistently get like 4th or something in dumber tourneys. Also numbers don't really prove how good players are in comparison to each other. Plus the results they use are like freaking old.
If you ask any good player, they'll have their own private rankings to decide who the best or worst are regardless of tourney results. National PRs are only good if they have national panels that travel all over and take these things into consideration not just raw data.
I mean, Razer at 16th then Dojo at 25th? Mikehaze at 30th or Anti at 48th? If you wan a really oddball one, look at Hylian in comparison to Phantom X or Dphat or Dmg. TX PRs should be the foremost source to rank these players, but look at how these PRs went.
I really doubt people who are ranked within the top 20 even pay attention to these rankings because they should be the most knowledgeable as to how worthless this is.
