CAN NICK CLEGG MAKE IT A DOUBLE?

*
Since I began my Interruption Coefficient spreadsheet last June, The Andrew Marr Show has yielded 46 relevant interviews. If you look at his Top Ten toughest interviews, as ranked by I.C.s, you see a clear and hardly unexpected result. As well as the I.C. (shown in orange and in bold at the end), I've also included the length of the interview and, before it, the number of interruptions (in bold and italics):

2. 18/10/09 Liam Fox Conservative 17 9.48 1.8

Today sees the appearance of Nick Clegg. Will he evict his near namesake from the Top Ten?
