10: US Dual Ranges with ZIP and Alt Name, 100% spelling senstitivity, 100% minimum match score
9: US Streets with Zone and Altname, used ZIP as zone, 100% spelling sensitivity, 100% minimum match score
With the same fields mapped and 100% senstivity and 100% minimum match, I'd expect the same results. In what way is the ver. 10 locator more "picky" under those circumstances? I haven't gone diggiing yet and really don't want to. My employer refuses to move to 10 without understanding the difference, however.
