Perhaps some sort of Coaching Level Program, where the only way to Get your Pass is to produce Results, even if you paid, if you fail you don’t get the Level. Perhaps with some sort of CF based written exam - So true CF style of coaching is producing the said results.
Eg
Level 1 coach - has produced a 11 - 11.25 runner (male) or Female equivalent time
Level 2 coach - has produced a 10.75-10.99 runner
Level 3 coach - a 10.50 - 10.74 runner
level 4 coach - a 10.25 - 10.49 runner
level 5 coach - 10,00-10.24 runner
Master coach - sub 10
