Parkour has levels like anything else, actually... You start with simpler vaults and falls and work up. My point is 3-4 ranks is what most professionals have in modules, sixes being exceptional....mall cop is 2-3, lone star 4-5, swat 6, maybe 7. Yeah, the scale keeps going but only to account for, if not the harlequins, at least the Micheal Jordans...
