I don't think you are talking rubbish GB, but I did the same yesterday and it didn't seem to help. I set off slow, 40% of total final time to CP1, but then didn't move on and finished only 2 min under my time of 2 years ago, so it is a pb, but when I last raced this it was my first hill season so I should have moved on more than that, I hoped. However mostly I just felt horribly cold and grey yesterday so didn't enjoy the actual run/ stagger.
