What is the Marketshare of the big three video editing (NLE) software packages? Cannot find a source to see market share or change for top video editing software tools used today.

The big three are:
Avid
Final Cut Pro
Adobe Premiere Pro (after effects)

I know Avid is still used by large film and movie productions.
But from the grass roots perspective, every day users, it seems to be overwhelmingly Adobe products. But this is based on my anecdotal personal perspective. Wanted something more concrete.
This kind of data is actually remarkably hard to come by.  There are a few industry reports available for thousands of dollars, but the best free resource I could find when I was searching was an informal poll that Dave Dugdale did.  It was an imperfect test by his own admission because it allowed both voting up and voting down, but it gives at least some kind of an idea of the rough market share.
