Hi Don, really sad to see a so low resonance of your thread. I guess the problem is you did not give a simple answer. Most people think in simple solutions and not in more complex possibilities. Hopefully I'm wrong.
Yes, it's a complex subject, and I am sure I did not do enough to simplify the concepts and start with simpler examples. I had some time off and just getting the Python program running and working through the first few examples consumed way more time than I expected. Someday I may try to go back and tighten things up but for now it is what it is... For now Life and Work is ramping up (new parts coming in to test at work, older son getting married in a few weeks, so we're pretty swamped).
That said, a lot of the threads I and others (e.g. Amir) wrote get buried in the overall wash of threads on ASR, especially now that we've grown so much. A lot of basic questions could be answered, or at least understood, by wading through the various tutorials but reading and assimilating them takes time. They keep getting views, though at a low level after initial publication, so hopefully are still relevant. I rarely use a dictionary but have one on hand for the occasion that I need it and would miss it if I did not.
No worries - Don
