Big end bearing - metal selection table

[kew]

I've never really noticed before because I always measure my crank pins and never use standard rods but,
In the table the marking is shown as 1-2-3 but in the list downwards showing the oil clearance and shell colour the pins are 3-4-5.
Am I missing something?

It's just how Honda marked the rods and crank to cross reference the shell size for that particular crank pin and rod combination. It could have bee ABC /XYZ or whatever they just chose that combination.
