Dear Jerry, If you got good M3, P4, P5 and M6 to work well and then follow up and down without too much trouble, then, by definition, you have a good temperament. Further, if the piano sounds good, it is a good tuning. Improvements are always possible, but the goal is a good tuning, not neccessarily a perfect temperament. The objective must always be to improve over the last tuning. When you lose your objective you stop improving and growing. It sounds like you found a good solution to a difficult situation.
