Why finding out the correct value? If you just don't 
\renewcommand{\arraystretch}..., you get the (result of the) usual \strut.

The fact that the name `\arraystretch' was chosen instead of `\arrayshrink' 
may indicate that it is intended to have a value of 1 or a greater one -- 
the choice is a design decision appropriately for the whole document, in 
order to get /larger/ distances between baselines of rows than the current 
\baselineskip in tabulars or arrays. In this case a manual \strut inserted 
by the author doesn't have any effect (at best).

So some values starting from 1 a little upwards may be "correct" from the 
design point of view, those less than 1 or more than, say, 4 are "wrong" in 
the same view.

Indeed I tend to wonder whether any LaTeX user has \renewcommand'ed 
\arraystretch at all.
