i don't think it's very useful. track is a team sport. your recruiting usefulness relates to how you compare to the current team. that moves around over time. that tool doesn't seem to spit out very accurate of a recruiting picture.
here is how you go. given your GPA and SAT, research a bunch of schools that you have a shot at being admitted. figure out ones with your major and in areas you'd like to live in -- a while or permanently. then research their track teams on TFRRS. TFRRS has all their meet results.
you then compare your times to the times of the current team. you don't want to know some vague standard. you want to know how you would stack up in a race with the current team. if you are faster than everyone, pick a harder team. if you are slower than everyone, go down the pecking order. you want to find the sweet spot and ideally you don't want to be the slowest guy the coach will let on the team, as you will spend 4 years fending off new recruits.
but short answer, that site is bonkers, and even when the school gives a standard sheet it may not get updated. you want to know what someone in your event runs right now and how you compare. research their race times, and only use the standards as guidelines.
last thing, if you are looking at D1 and several seconds behind their worst runner i would save my approach until i am competitive with them. D3 is different, but don't waste a bunch of time contacting schools you aren't competitive for, and it might make it worse if you run the time next year if you contacted them with a slower time below their walkons.
