I get the horn whenever I am enthusiastic about punting, helped by having great punts. This time last year I had a long lay-off thanks to illness, but was very eager to punt. As soon as I got better, I punted again. From that point until early October last year, my enthusiasm often varied. My least enthusiastic period was July where I did one punt (which was awful).
However this year I don't have much of a desire to punt. My last one was a few weeks ago which was OK but nothing special.
