Ironman Waitlist Success?

Anyone had success with IM Waitlists this year? I signed up for wait lists on a couple I want to run, but was wondering what the odds were a slot would open.

never seen this waitlist idea, is it on all races? Could you share a link. Thx

“Little Debbie IRONMAN Chattanooga presented by McKee A Family Bakery has sold out of general registration entries. Join the waiting list now to receive race updates, and notifications if new registrations become available. We look forward to seeing you at an IRONMAN starting line soon.”

I asked the same question here last week and nobody has heard anything from them. I’m on a couple races.
