Yeah, it does sound like a lot of work to me, too, but I can also see the benefit of it. Sort of. Yes, you can pick up if one of the animals isn't growing properly, but if you are observant while feeding them, you would hopefully pick up any serious problems anyway. I'm sure record keeping is very useful when you keep more than a handful of snakes or breed them, but knowing me, I would get a little paranoid if I got too much into it.
