Ok. Got the probes figured out. The original probes were of type Resistance. The new ones are obviously thermocouples. I had to do some controller rewiring.
Lets just say that you are absolutely correct on both fronts. The probes are in the wrong locations and the new thermos are far superior.
The initial setup was with the new probe in the original location. I put a kitchen frying thermometer in the suggested bolt hole. Just look at the different temp readings. The initial roast was so off I ditched the Artisan graph of it and beans went to trash.
Here is the probe in the new location. The temp readings much more accurate. Artisan graph shows temp readings at various roast levels. The FC estimate was just about spot on!
Feel free to comment on the roast itself. I kept the airflow about the same the entire roast (about 30%), just enough to get smoke out. I dropped in with gas at it's lowest possible setting and let the roast go for about 1 min. Then I turned gas up to roasting pressure (1 WC) and left it there until just about FC. Then I turned the gas down just a little and let it roll all the way through until 2nd crack.
I will have to work on the airflow probe next. Your recommended spot for that is probably also good.
