You're eligible for a slot based on your age group for the current year. If you are racing a 70.3 this year, you'll be in the 55-59 AG and will be eligible for the slots allocated for 55-59 AG for Worlds. Then next year you will race based on your current age and race in the 60-64 AG at Worlds.

Now that you explained it, yeah that makes sense!
And with the extended qualifying period, this does open up a bunch of possible options.

Slots are allocated based on your age the year that the qualifying race occurred; but you will race as the age you are the year that Worlds occur.

For example (I was on the cusp of an AG too - in 2022 i was 39 and was in the roll down for Lahti spots as a 35-39 year old. However had I taken one of the spots, I’d be racing worlds as a 40 year old since I turned 40 in Feb of 2023.

Well, since UKnowEverything, then I will accept your explanation :-)
