I know that this is region specific but even it I test the major Geo's these keyword are still on pos 1 or 2 but never on 3 or 4. How does this get reported and are others seeing this as well (It may be G trying to get us to bid more :-)
And in either case, you are always seeing an average of all the positions your ad has held in the specified time period, rather than your actual position at the moment.
And as we're all aware, ad position can vary from search-to-search, depending on what your competition is up to.
Lastly, a quick reminder that 'date range' is a sticky setting that always defaults to whatever you last set it to.
