just registered Aperture Inspector and am using it for the first time. The Camera Usage Over Time report isn't right. I loaded images from a new camera just before running the report. The images were all taken in the month of May 2012. the report shows 2012-04 16% and 2012-05 2134 % (?). The % total is actually the total number of images. the report didn't show anything for number of images.
And before you ask yes the date and time on my camera are correct.
Is this a known software bug?
BTW: a nice app; I bought it to help me decide what lenses to add to my kit.
