It was more esoteric than I wanted to address in the Newsarama piece — especially since I couldn't prove an alternate case — but several observers and I noted some strangeness in the Diamond indexed reports for the month. In a nutshell, the index numbers cluster very closely to publisher internal reports for the Week 1 shipping products — becoming roughly 2% too high for each successive shipping week. Then there are a couple of items in the list that did not ship in January at all, but in the first week of February. My theory is that somehow the public chart and the publisher charts do not reflect the same exact grouping of ordering days: if, say, some February reorder activity entered the January chart, that would explain a lot (but not all) of the variance. The Week 1 numbers were solid, so I went with that for the Order Index figure — but, as always, my reports are subject to revision should we get revised information (or clues from the February chart as to what actually happened). Caveat calculator!
