The CORRECT way to change the rein.

6.5 or 7?

When changing the rein, you need to be firmly on the track beside the marker your headed to when the rider is exactly beside the marker. So many riders head straight towards the marker, then only get squarely on the track a few metres after the marker.

If I'm between a 6.5 and a 7 for the way of going, and the accuracy of the change of rein is good, then it's more likely to be a 7 than a 6.5.
