In the text-scale-adjust docstring,

   Each step scales the height of the default face by the variable
   ‘text-scale-mode-step’ (a negative number of steps decreases the
   height by the same amount).  As a special case, an argument of 0
   will remove any scaling currently active.

That is good but the user might want to simply go from
12 point font to 13 point to 14 point to 15 point...

Alas there is no possible multiplier that will achieve that.

So the docstring should mention what to do in this case.

The command in question is for interactively visually adjusting the font
in the current buffer -- it's not for selecting a specific point size.
If you want to do that, there are other mechanism for making Emacs use a
specific font, but it makes no sense to talk about that in the doc
string of this command.

So I'm closing this bug report.
