Project your whole discipline from one swim
Enter one event and time. We find swimmers in our database who have gone a similar time in that event (same stroke, gender and course), then look at what those same swimmers did at every other distance in that stroke.
For each event we rank that cohort by final time and report the median, along with top-25%, top-10% and top-5% reach times and the cohort average.
It's purely data-driven — no formula. Bigger sample sizes mean more reliable projections.
