It seems clear that NDP under tracker XB1 in Jan which then made VGC look like they overtracked, overtract XB1 in Feb which made VGC look even worse, then was possible back on track for March.
Fact is while NDP numbers are accurate over a 2-3 month span they are not too good month to month, the way they adjust is by basically taking the current total- what they were tracking = current month.
