I have heard/read that those that have done the max number of positions had issues with distances etc., a possible glitch in the program. Maybe try just 4 locations to see what that brings up? Even on the 3808, some are still mentioning calibration issues and it appears to me, many have done the full 8 poisitions allowed.
