1-second max watt record

Hi everyone,

Coming here because I feel like I am losing my mind.

I have been using Zwift for few months and I stupidly love looking at those max watt going up (though still very low given my level) - a bit obsessed by this to be honest.

I was really proud recently because I saw somewhere after a race that my max 1s interval wattage reached 600W (10W/Kg)- I was convinced it was on the progress report at the end of the session.

Today while doing another session, I noticed that I apparently beat my 5s record with a 598 but the 1s interval score was not appearing anywhere.

Checking on Strava, the minimum interval they provide info on is 5 seconds as well so I am starting to wonder whether I imagine it.

Do any of you know where I can find this 1s interval max wattage or whether I simply imagined it?..

Thanks a lot!

Just to give a bit of context I am only using Zwift and Strava to track my max Watt per interval.
