In my experience of this data over many years then if you are 20% too high one week you are unlikely to be 20% too high the next and so on unless you are consistently under / over tracking. The errors will even out over time and as we slightly adjust in light of new figures they will gain accuracy further. I think that at any one time our LTDs will be accurate to the nearest 5-10% as we get shipment updates and so on and have reference points from which to compare, but the weekly / monthly breakdowns may be less accurate but then does that really matter too much? |
Bleh, I should have just let you say it.
