Three half steps probably qualifies you as a primo candidate for my "HeldenTuner Award". I have often seen the same affect of a huge pitch raise. My conclusion was that such a large change in the total tension on the back causes it to flex a bit. As the tuning pin position corresponds to the string location (left-middle-right = low-middle-high) that the top of the pinblock ends up skewed relative to the bottom of the pinblock. Hence, different "results" from the same process.
