It makes perfect sense to me. If you using animation, then you want it to run it's course. So repeat it once is best option.
You are using it in a none animation way, which is why you find it frustrating. (I use it this way to)
You don't want to change the default 1. What would be nice is to set the speed to 0 as default, that way it won't cycle till you set the speed at say "5"
