I have a question about this tool... I Have used it many times before and had good results. However, I just moved my Metallica Pro machine to a new house, and as part of reinstalling it I thought I'd crank the leg levelers all the way up and get the machine leveled from scratch at the new location. With all legs all the way up, Pinguy tells me that the back is "9.9 too high". I interpret this to mean that I needed to raise the front legs higher off the ground... even though the machine "felt" like the right back to front slope. So, I crank both front legs up about an inch, yet Pinguy tells me that it is still "9.0 too high". At this rate, the machine is going to be visibly flat before Pinguy ever tells me that it is set for 6.5' pitch back to front. Obviously I am doing something wrong... any pointers?
