Hi Trevs, really interesting topic!
Could you please clarify something - you say that "From 31st Dec 1963, the chart was compiled on a Tuesday" - does that mean it was announced on a tuesday lunchtime in 1964, or did that only start in Sept 67?
Also in the event of tied points (and both fell/climbed), does it matter which was a bigger faller or climber in terms of separating positions, or would it be a tied position?
Many Thanks!
