You should also note that coaches all use the AI, so when talking to a coach about possible recruitment it’s helpful to know what your AI is, along with your swimming times. Coaches mainly care about your athletics, and then want to know your AI to see how competitive you will be.
It’s also good to know how your swim times stack up. Cornell lists specific target times for recruitment purposes, which may be useful as a general guide to Ivy standards:

So if you can say something like “I’m a swimmer with a sub 55 second 100-meter free time [or whatever is applicable to you] and an AI of 210” then you will definitely be speaking their language, and will hopefully get their attention.
