I changed the shift speed from 1-5 and that did not have an effect. I first noticed it when I pulled the lever at 4000 rpm under moderate acceleration and the car did not shift until over 5000. This happened for about 3 days and then disappeared.

I searched on this topic and did find many threads on the non-responsive shifts but the SIB's and threads seem to be for cars which had production dates much earlier than my car. I am was going to bring the car in and have them update to the 213e (or 231e) software but I was not sure if anybody else had seen this issue and had software updates to correct it.
I'm no ///M engineer, but I wonder if what you describe occurs in more cars. Based only on the emboldened text, if others are experiencing similar tranny behavior, you may have stumbled onto something fairly extraordinary -- adaptive shifting -- that learns driver shift patterns then compels driver to endure "playback".
