Nope, do what you want.
I count them. I ride kiddy coasters for the +1s, but I've never been in a situation where doing that is compromising something else.
Obviously, bigger and better coasters get priority, and if I found myself short on time, I'd skip the smaller stuff; it's just never happened.
That seems to be the main criticism levelled at people who enjoy the counting aspect: you're wasting time when you could be riding x,y and z. No, because x,y and z have been done, more than once if they were good, and will probably be ridden again before I leave.
I physically can't do multiple back-to-back rerides on intense coasters anymore; I start feeling slightly nauseous and get headaches, so taking a break to do other stuff, then going back later, works really well. If someone can spend all day whoring Zadra, Hyperion and Abyssus, more power to you, but I personally wouldn't find that enjoyable at all after a couple of rides on each.
