Well I've done another analysis, but what I realise is thay by doing them I have got a lot better at it, and therefore I think I made some mistakes in the first few. So I've decided to keep plugging away, BUT also to go back and double check the ones I've already done, this will take a while but its peace of mind more than anything. I think I will do this by double checking 1 every lunchtime and 1 every evening.
