Sorry, I don't understand why you need to count clicks.  Typically
when users change the text scale, they just turn the wheel until the
size they get fits their needs.  Making text-scale-mode-step smaller
causes finer changes, so it's easier to be more precise in finding the
desired scale.

Can you explain how your proposal makes it easier than that, and why?
