Well, I tried the bike without the speed sensor today. I was even able to compare the same route with my new bike and the bike with the TSDZ2. Short summary, if you tied this you would immediately value the new bike.
The conditions were the same, a pretty steady headwind at about 20-25mph on the same route. The reason for trying the two bikes back to back was actually highlighting the weakness of the Priority Current.
I had to make several trips today with meetings in three different buildings. Very simply, I ran the battery in the Priority Current down. That said, I expected that and I made sure that I was near my house at lunchtime. I stopped and switched bikes. Both bikes are 48V Mid Drive bikes with NuVinci N380 hubs. The route was basically: Home > Building A (~3mi) > Building B (~2mi) > Building C (~2mi)> Building A (~4mi)> Building C (~4mi) > Home (~1mi) (switch bikes) > back to Building A (~3mi).
The TSDZ2 equipped bike does have a much larger battery. I am considering wiring it in as a second battery on my Priority Current, however, that is its own bag of worms.
I decided to test your theory. To do that, before I left, I removed the speedometer pickup magnet. Short story, it made no difference. I was still downshifting to go faster. I was still going between 13&15mph for most of the ride. This was slower than the Priority Current had gone on the same stretch twice today. I tried high cadence, low cadence (my normal ~65) and throttle only. With the throttle, It approached 15 mph.
With well over 1,500 miles, on the TSDZ2, I still hold that the TSDZ2 is a good assist motor for a recreational rider who just wants a bit of help. It just lacks the power for extreme conditions, like high wind commuting routes. There is no way that this is a 40mph motor, as your calculations showed for my gearing. However, when downshifts increase the speed, the motor is powering out. There is nothing wrong with that, it is what it is. I just wanted a little more.
The TSDZ2 may find a home in my velomobile, I think that would be a good match. However, the step back to the TSDZ2, for my normal commute, today assured me that I have made a good choice in getting a different commuter.

Did you try unplugging the throttle and restarting it? I just rode a 350W today and it is fast. No throttle and no speed sensor.

I will give it a shot on the way home. Of course, that wind will be behind me, not a real A to A comparison.
