Thanks much for adding the price/percent column.
The reason I suggested to add percentage-change colums for quantities was to identify movements of sweetspots. In this respect, for Distributor #2 sum of inventory and backorder quantities would be more appropriate than either of the two quantities of the table alone - although it still lacks the timeline-dimension, pointing to trends.
Consequently, as Distributor #1 without backorder-quantities, the percent-change of inventories could be rather misleading, so it should not be added there.

p.s: Do with it whatever you like. If that would be nothing at all, absolutely fine. :-)
