FWIW, I usually mine in a pattern with central 2X2 corridors, with 1X2 tunnels branching off, leaving two blocks in between each tunnel. That way you can see all the minerals without having to mine out every last damn block.
I'm told the most mathematically efficient way is to do what you described but leave three
blocks between each branch tunnel. Since most veins are 2x2 you'll never miss any by leaving 3 blocks in between.
I suppose, but I think the completist in me would get annoyed at the hidden row.
