How to compare swimming times properly
Comparing two swim times sounds simple. It is, as long as you are comparing the same thing. Most confusing comparisons come from quietly mixing different events, courses or conditions.
Direct answer
Compare swimming times properly by matching the event, distance, stroke and course first, then accounting for age group and race conditions. A fair comparison is like-with-like; mixing courses or events produces a number that looks meaningful but is not.
Match the event and course
Only compare the same event and distance: a 100m freestyle with a 100m freestyle, not with a 100m backstroke. It sounds obvious, but mixed-event comparisons creep in easily.
Then match the course. A 25m pool time and a 50m pool time for the same event are different performances because of the number of turns, so they belong in separate comparisons.
Account for age and development
Comparing a swimmer's time now with their time a year ago is fair and useful. Comparing two different swimmers of different ages and stages tells you far less.
Within one swimmer's history, note where an age group or course changed, since those points break a clean run of like-with-like times.
Mind the conditions
Hand timing and electronic timing are not perfectly comparable, and a relay lead-off, a heat and a final sit in slightly different contexts. Note these where you can.
A swim at the end of a long, tiring meet weekend is not the same as a fresh swim. Conditions do not invalidate a time, but they help explain it.
Let the tool keep it honest
The cleanest comparisons come from records that already separate event, course and round, so you are never accidentally comparing across them.
PB Pathway keeps short course and long course apart and tracks times by event, so comparisons stay like-with-like by default, and a swimmer's progress reads fairly rather than through a misleading mix.
FAQ
What is the most common mistake when comparing swim times?
Mixing courses, comparing a 25m pool time with a 50m pool time for the same event as if they were the same performance.
Can I compare my child's time with another swimmer's?
It tells you little. Comparing a swimmer with their own past times for the same event and course is far more useful.
Does timing method matter?
Yes. Hand timing and electronic timing are not perfectly comparable, so note the method where you can.
Why separate short course and long course when comparing?
They are different racing contexts because of the number of turns, so they should be compared within their own course.
How does PB Pathway keep comparisons fair?
It separates short course and long course and tracks times by event, so comparisons stay like-with-like by default.
