This is what I said a few pages back... Each Head to head whether it is 2 chasers or 5 chasers - they pretty much always get 1 question wrong (minimum, sometimes more, very occasionally don't get any wrong). So you are more backing yourself on how many questions can you afford to get wrong and attributing 3-4 secs per question wrong. (I.E 50 seconds - 2-3 Qs wrong. 40 Secs - 5-6 wrong). It's more the rhythmn that does folk (and the Chasers) that often leads to those sticky moments in a H2H.
