Swimming speed needs tuning...
I think after Adventure Awaits EP skilled sims do speed up quite a bit in the pool. That is fine for top skilled sims, but right now an elderly female with fitness skills of 6 is swimming sooooo fast that it just looks a bit silly. She reminds me of an insect trying desperately to find a way out, constantly hitting the edges. She is too old to swim this speedy, besides she is "only" skilled 6 - what will her speed be when she is at 9...?
I think it should require a higher skill level to swim this speedy. I'm not sure how many speed levels there are, maybe they all should just be moved a couple lvls up? About elders, I think they should drop a couple speed levels due to age alone, regardless of skill. My elderly female looks more speedy than a natural trained teenager would be... Not saying that a top fitness skilled elder can't be speedy, but slowing down a bit would still be speedy. It should require top skills, or maybe even skilled elders should slow down a bit in general.
When in the pool, after AA EP I notice that many more sims are entering the pool when I arrive a lot. They often are in the exact same posoition, about to enter the pool, doing exact same animations. I takes a while before I can see how many they are. I wish the pool was slightly less attractive. It feels weird that 5 sims are entering from the same spot when there are plenty of other things to do on a huge lot. I suspect it was programmed in because of the new diving boards and pool upgrade in general, I hope it won't last. At least it's better than sims always grilling food when entering a lot...
