Why don't you then if it's so easy?
I never said it was easy and you would need two people to do it but if you had it down to a tee it could be done. One race watcher, one clicker, i'm sure you can see that it's possible....
I make my living working a full time job however and don't have a partner or the bollocks to do it. If you wanted to give it a go though i'm willing to entertain the idea...
