I think that depth completed is a pretty universal thing.

But it may be that different folks see what's important in different ways. So, when you display 7.10 depth, that means you've searched seven full ply, plus 10 root moves of the eighth ply? When I display 7/10 depth, it means I've searched six full ply, plus 10 root moves of the seventh ply. That is, I terminated the search at ply 7, move 10. That seems like the proper way to do it.
