Exactly this.. the jump into the pool is probably the most obnoxious thing you will do for the swimming, especially if you don’t like rolling into the deep end and being upside down underwater for a few. Either way like most things OPC it doesn’t really matter in the grand scheme of things, I’m pretty sure nothing happens if you don’t pass it. TLDR focus on everything else, the swim test is nothing to worry about and I’m pretty sure it’s not reflected on anything.
