Thats what I do, I want accurate data, the only thing that let's gg down is the putting side of it in how accurate it isn't. I take an extra card out with me and I pace out the length of putt I have and record it then edit later. If I sink a long putt I will tap the hole position to mark the hole and delete later.
I am an advocate of Game Golf, but a word of caution on your desire for accuracy. I read elsewhere that any public GPS system is only accurate to within a few yards at best, so suspect you shouldn't rely too much on putting distances, especially those close to the hole.
