I don’t on the whole disagree H, but there’s different ways to go about it. The first ever OW swim I did, the organiser of the venue just got one of the kayaks to paddle around near me for my first loop to make sure I knew what I was doing. Had he said I needed to pay an extra fiver or tenner for that, to cover the effective 1:1 coverage, then fair enough. But the style of induction where you need to book a specific lengthy slot at a specified time is just a major barrier to entry.
There needs to be some level of appreciation for prior experience, however you go about it. I have the same criticisms with my club for road riding. They insist on an induction to join group rides, which is absolutely fine in principle as you don’t want newbies to be unsafe and bring others down (although they don’t hold them very often), but there is zero leeway for uber-experienced cyclists. You could have Cav try and turn up to a group ride and I’m sure some of the guys would just say “have you done you club induction yet?”
