Been watching the Glynhill results on line and have been amazed at the number of times teams have failed to hit the house in the last stone draw. Things seemed to be gradally improving as the weeked progressed - however in the last draw (session 9) five of the twelve teams missed the house totally (assuming the results on the website are correct).

What's the reason for this?

I see the LSD is being played at the end of the game and the result is carried forward for the next round. Is the ice beginning to fudge? Or is there another reason?
