Zoom Lenses — do you use the full range?

I’ve heard it asserted that many photographers use only the extreme focal lengths of their zoom lenses.

I haven’t thought this was true of me, and today I had Lightroom plow through the numbers for a wedding a shot last Saturday (plus the rehearsal Friday); and it isn’t true of me.

Focal lengths used with 12-40/2.8
Focal lengths used with 40-150/2.8

I do however use them at their long end more than elsewhere; no surprise there, I’ve always been a telephoto guy.——
