I put the “not important, and you can estimate if you lose track” option, just because I hate to see people get so uptight about “doing it right” that they lose track of the spirit of the prayer in their service to the letter of the prayer.
However, I’m a total touchy-feely person, and I find that personally, I am much better able to focus on the meditations if I have a rosary in my hands. But since that’s not always practical (I second the fellow runner who prays the rosary while putting in the miles!), I try to not get caught up in it.
That said, a quick count of my house reveals 8 rosaries for 4 people, two of whom are under the age of 5. And that’s just the ones I can think of off the top of my head.
