Even better -- I found that I had, in fact, measured correctly, and all four holes ended up exactly where they needed to be!
I learned the hard way to avoid measuring for mounting holes. Use the cabinet itself as your template! If possible, I drill through the cabinet mounting holes with the cabinet in place on the pad. That method is idiot proof. if that's not possible, then set the cabinet in place, mark the holes on the pad, and then move it to drill. Be sure your drill bit doesn't drift!
