I do the swim test a couple of times per week anyway
I think all divers should be able to do all of the basic skills. The swim test (IMHO) is more of a comfirmation of physical fitness and could easily be replaced with running or cycling or something else. Unfortunately, many OW divers let these skills lapse, and also get out of shape. So, I commend this scuba club for trying to ensure its members stay current on their skills, but at the same time it probably does drive some members away (maybe they aren't interested in retaining those members). Personally, the cost would be the indicative factor for me participating in such a club. I have no problem with practicing basic skills and it would be a bonus to get a little exercise at the same time, but not interested in paying for the opportunity to do so (other than my share of the pool time).
I'm not sure what you mean by "OW pool session". Is it just one or all of them (i.e. the whole OW course less the academic portion)?
I will agree that at some point it does become overkill.
