The value and position in the grid depends, I think, on the actual
adapter it detects.
e.g. on a system with a Sheepwalk RPi2 I see
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- 18 -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
on a system with a Sheepwalk RPi3 I see

10: -- -- -- -- -- -- -- -- -- -- -- -- 1c -- -- --

50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
Both work fine.

So it's the same value using -r & -y, I don't know if that's good or bad?
I have always only seen 1b, and nothing else when using -y as in guide
I was following previously (before Buster install).
