Just as a reminder - Interruption Coefficients (I.C.s) are calculated by dividing the number of interruptions by the length of the interview. The higher the I.C. the tougher the interview (as a rule). I.C.s of 0 have contained no interruptions! Interruptions are only classed as interruptions if they stop or significantly alter the speaker's flow. Muttered 'wells' and the like are classed as 'abortive interruptions' and are not counted. Those that share an I.C., say of 0.8, are sub-ranked according to a hidden (inferior) measure called the Questions Coefficient, which is calculated by dividing thee number of questions by the length of the interview. The more questions there are, the likelier the interviewer is holding the reins in an interview. That means that everything is ranked just where it should be!

As usual I will begin with the full list (with apologies as ever for the lack of punctuation!!):
