Hi Tom, you made some valid points!

Your response on the subject of changing AIM settings made me think of earlier discussions I had with you on Control System issues and it reminded me of a control system problem I ran into as a greenhorn engineer in a Proctor & Gamble Pulp Mill in Grande Prairie (Alberta) in 1976. The problem there was caused as a result of not adjusting the settings on a Level Controller. My Short Story on this became a bit too large for directly placing it here. . .I made two 2-bit Short Stories of that experience on how I solved the Control System problem in that mill:

Changing settings of a control system has nothing to do with emotion or predicting the future . . it is simply a matter of adaptation of the response for a system that encounters different external disturbances or when the system itself is changing.
As my story demonstrates a system can operate reasonably well with wrong settings, but then it might not operate at its best, and when it encounters a “curve” in the road the “car” will run off the road sooner than when the settings are "perfect". . .To get these perfect settings one has to adjust the settings frequently with changing conditions. . .This is used in some cases, as you know better than most on this forum, with the application of automatic adaptation of the control system parameters in an control algorithm.

Regards,
