I hope I'm not on your toes here Femurat,
The "tightening" of the contact points at 50 hints at a gate. Right below that he has "amplified" the area around 50 by taking readings every increment to get a more defined view of the suspicious area. After he did that he found it was actually 51 not 50.

Not exactly, most locks read in a certain order, wheel 3 first, then wheel 2, then wheel 1. But not all of them read that way. This graph does tell which number in the combo he found, it just shows a number.

I'm not sure I follow what you mean .... but if you measure one wheel alone then you know which wheel the gate is on (that wheel) . If you measure multiple wheels, then you have to do extra tests to ensure you know which wheel a gate is on.

Yes, the right contact point is the sloped one. Because of the slope of the drive cam, good indications are more obvious on the right contact point.
The left contact point should feel like a brick wall by comparison to the right contact point.
fgarci03 wrote:So it would make sense that on the graph, the contact point near 6 would show a much more suddent variation, and a fainter variation on 12. But it's the opposite. So what am I missing here?
Your assumption about the left contact point being easier to read is right and wrong at the same time.
It's hard to MISS the left contact point, but because it is NOT SLOPED like the right contact point, it is more difficult to see differences in it.
