Inspired by the USA Swimming Age Group Motivational times, and my inability to find any Recent Masters examples, I've created my own Motivational Swim times for those of us 18+.
Here is the Methodology:
AAAA time is the published USMS National Qualifying time for 2024.
Time is Converted to a Seed time, and then back to lower standards using a formula published by Jim Patterson in 2012.
Adjustment for all ages is +5% from Seed Time for all ages.

Hope this helps you set your goals for 2024 and beyond!
