2345 Commonwealth Avenue, Newton, MA 02466
524 Lowell St, Peabody, MA 01960
both plotted miles off.
But I tested my own address after that on a smaller street and it was also about a half mile off.

I’ll have to look into the geocoder setup. It was over a year ago I set this up, so kind of forget how that all worked. Will check that out.
