OK, I 'think' I have the third number of the lock combination triad.
Here's how I did it.

Rotate the dial CW three times and then stop at the zero.
Tension the shackle & turn CW, successively, to each sticking arc.
NOTE: There will be 7 half points & 5 full points, e.g.:
1st sticking arc was between 2 & 3 (i.e., sticking point = 2.5)
2nd sticking arc was between 5 & 6 (i.e., sticking point = 5.5)
3rd sticking arc was between 8.5 & 9.5 (i.e., sticking point = 9)
4th sticking arc was between 12 & 13 (i.e., sticking point = 12.5)
5th sticking arc was between 15.5 & 16.5 (sticking point = 16)
6th sticking arc was between 18.5 & 19.5 (sticking point = 19)
7th sticking arc was between 22 & 23 (sticking point = 22.5)
8th sticking arc was between 25 & 26 (sticking point = 25.5)
9th sticking arc was between 28.5 & 29.5 (sticking point = 29)
10th sticking arc was between 32 & 33 (sticking point = 32.5)
11th sticking arc was between 35 & 36 (sticking point = 35.5)
12th sticking arc was between 38.5 & 39.5 (sticking point = 39)

Here are the 5 full points: 9, 16, 19, 29, 39.
Looking only at the one's digit, we eliminate the duplicates.
That leaves us the oddball 16, which is #3 of the combination triad!

Doublecheck #3 of the triad using this more exact method:
