How was MySwimSplits Race Review Calculator created?
Over 2000 data points from the top 10 fastest race times in history for each Olympic event were analysed. Every split in each swim is captured, converted into a percentage of total swim time. All the splits are then averaged out across the 10 fastest times in history to create a formula that can be used to reverse engineer out a future Goal Time or to review race results.

How does the MySwimSplits Race Review Calculator work?
First off, the swimmer selects the Stroke and Distance of the race they have competed in. The swimmer will enter in their split times that they have swam and hit the Calculate button.
What happens next is – the swimmers results are compared with the Ideal Splits (the algorithm that came from the top 10 fastest times in history).
