It depends on how obsessive you are.
Honestly it isn't that bad, because how I evolved in to using it I don’t fuss over specific pictures. I do a group and do a quick scan of the pictures, maybe less than a few seconds looking at each frame to determine where it hit. I go through them on full screen view, pick a number on the outside edges of the DOF front and back then scan them and mark them with stars, like one for front focus, two for on and three for back. I use Adobe Bridge and just look at the number count to see the averages.
How many times have we seen someone post three pictures and think there lens is front focusing? Honestly if I do a group of 40 pictures there maybe four or five in a row that front focus slightly then the rest go behind. What I have found is the cameras AF system is not at all as accurate and consistent as we would hope. I think it is more accurate and faster to quickly review a thousand shots than it is to over analyze 40. I can do a lens in less than an hour, it doesn’t take that long.
I like the idea of this software. Tested with 1000's of shots seems to be kind of light for testing a new product.
