One other thought, Brian and all, on doing a bridge chart for a missing Christmas chart. I’m not necessarily advocating for this, just mentioning it as a mathematical thought / possibility. I think we briefly discussed this before, up thread somewhere.
I / we have read somewhere that sometimes it could be that a published chart after a skipped week was not a chart for the preceding 1 week period, but was a chart summed up over the prior 2 weeks !! Which would mean that the dealers summed up their sales over a 2 week period, ranked them, and submitted the rankings to the music paper chart, who averaged them all together.
So in trying to deal with this 2-week chart situation, we could have DIFFERENT scenarios of what would produce the best truth for a missing chart:
a) skip the missing week
b) freeze the missing week chart with the chart FOLLOWING the missing week
c) construct 2 new charts for the missing week AND the following week
Example: let’s say MM skipped a chart for the week of Dec 27, and we know the following week chart for Jan 3 was averaged from the dealer charts over the prior 2 week period. Perhaps MM told their dealers in advance to produce only 1 chart for the 2 week period. Our options would be:
a) just skip the missing chart of Dec 27
b) freeze the missing Dec 27 chart, but not with the preceding Dec 20 chart, but rather with the following Jan 3 chart
c) create a bridge chart for Dec 27 by averaging the Dec 20 chart with the 2-week Jan 3 chart, AND create another bridge chart for Jan 3 by averaging the 2-week Jan 3 chart with the Jan 10 chart
Which option would be closer to the truth?
Most interesting I must say, but just a thought. Please, no one strain your brains on this, ha…
