It is always dangerous to go head to head with an academic, but in terms of the 5% and the 10%, my reading of the Organisation for Security and Co-operation in Europe report is that it is a 10% variation between seats, not a 20% variation. May I clarify, Dr Renwick, that when you talk about the 5% difference, that actually gives an overall difference of 10% between seats, whereas a 10% difference would give an overall difference of 20% between seats?Q
