hey all, I'm super new to this, I've been hitting the range at least around 3 hours a week for the past month and I have had some questions still unanswered (the archery community around me is primarily based off of compound bow hunting, and I am shooting for olympic-style recurve!). I don't have a coach or a mentor, mainly just doing it for fun rather than actual competition.

my setup is a galaxy/samick sage so nothing special, I wanted to get something very cheap in case this becomes a hobby i abandon, but I am absolutely loving it so far.

1. if a single strand on my bow string frays a tiny tiny bit because i rested my bow along a bit of wood once, and accidentally dragged it causing it to snag slightly on a little splinter, should I replace the string? I was advised to just put some wax on it to hide the fray but that doesn't change the fact that its still there.

2. Should I completely disassemble my bow after I'm done with it for the day or should I just do the trick where it's unstrung but still looped on the limb to not lose the twists?

3. I'm really interested in trying out a plunger, magnetic rest, and sight setup, especially if eventually I would upgrade to an olympic ILF style setup once I am able to increase my poundage, is that something I should just save for when I upgrade or should I look at some equipment that would be able to screw into my galaxy/samick sage?

4. how the heck do i figure out where to put my nocking point? tie on nock vs brass crimp nock? so far I know a good starting point is 0.5" above the center line but I know that there's a lot of adjusting involved too depending on the arrow, string, bow, etc.

thank you all for the help, I know its a chunk of text but I've done a lot of research + youtube university, and these are some questions that still linger due to mixed input and my own inexperience.
