I then tried to confirm potential gates between 9-10, 64-72, and 80-86. To do that I parked 9,10, 67, and 83.5 at W1, W2, W3. Here's what I found:
Starting with 9 and 10. Although the graph wasn't going that low, it seemed to demonstrate a gate signature on wheel 1. So, I ran high/low tests and confirmed that wheel 1 was driving the pattern (contact area was widest on wheel 1 when running the high-low tests).
I probably would have tested gates by parking at something like 90 and running the other wheel through the area, in isolation. Partly because the contact area seems in the way a little, although it's not too bad.
I then parked wheel 1 at 9.5 and isolated wheels 2 and 3 to see whether any additional gates could be identified. Nothing is really popping out here from what I can tell, though when running wheel 2 I only went in increments of 5 (rather than 2).
I don't think doing increments of 5 is warranted at this point, also I just don't believe in it. Yes it's possible for numbers to be set this way, although I've never personally encountered it (although I know people who have). I just think it's a low percentage thing to spend graphing time on
The other thing...why are you not taking readings in the forbidden zone? The last wheel isn't supposed to be set there. Doesn't mean it isn't, or that wheels didn't shift, or a most useful area isn't there. Test all the area of the wheel.
I looked at 69 and only thing slightly interesting was possible gate signature on wheel 1, or is this just random fluctuation given it's only changing 1/10 of an increment and goes back down again after the possible gate?
It showed up twice. If it only showed up once I might discount it, but this is twice back to back. That might be something. And I know I said that about 5's and 10's, but would you look at that, it looks like it's centred on 70. I might park that wheel there and see if you can't get a better reading on the remaining wheel. Or at least confirm your gate at 9-10
I then decided to check whether I could get a gate signature on 83 or 84. When I ran 83-AR-83 and 84-AR-84, I saw something peculiar. Somewhat of an odd gate signature, but the lowest point I've seen yet in my graphing. When running high/low tests on 83 and 84 they did NOT show on wheel 2 but contact area was consistent across all wheels. What does it mean that 83-81-83 and 84-82-84 are giving me my lowest right contact point readings so far?

83 area is looking not bad, although I though 90 looked better. Check out both those areas maybe?
I'm confused by your approach, why not run wheels 2 and 3 together after parking W1? Or did you just not show that graph?
I hope some of this helps, sorry it's a little scatterbrained
