The scores we get are a tangible means of measuring our success. Just as Edinburgh 101, Edinburgh 67 ..... Edinburgh 17 signs tell me I'm getting nearer home after a long drive back from where ever archery tournament.
The thing is we shouldn't be working on a score

we should be focusing on something else while we shoot. Whether its something abstract, or something we've been working on. Yes, we can empty our minds and let it flow, but most of us are at a stage when we are working on something and I've often found the most successfull days are spend focusing on one thing - the placement of a hand, the position of an elbow, the direction of a follow through, keeping a positive mood etc etc
The oucome of all this - the SCORE

can give us the motivation.
