For the 100m sprint, what is a good sprint time to be recruited? For a female.
Look at their 4x1 relay team. Are you within 0.1 or 0.2 of their slowest 4x1 relay team member?
There is no point talking about recruitment times, because you don’t even have a reliable one.
You and the nearest thing you have to a coach need to send a video to Stanford Track and Field showing you on a 100M course even if it is with hand timing.
If you really are serious, the thing to do would have been to make a special trip to any open track meet where fully automatic timing would be employed. That way you could have gotten even one official time.
The fact that this is coming up once you started looking at admission competition to the Ivies and Stanford makes it substantially less credible by itself.
