Now (while you are outbound in the procedure turn) mentally calculate
the time adjustment required by the headwind component of a variable
23-knot wind from 32 degrees off the nose which shears twice
somewhere between the time you start the approach and the time you
finish it, add the errror introduced by the fact that you don't start
the timer EXACTLY over the FAF, further include the error you made
in the mental interpolation of the time required for the approach
because your airspeed is somewhere between 90 and 120 knots, now throw
in the the fact that said airspeed will probably will change 4 or 5
times along the way, and we'll discuss the accuracy part.

Oops, I nearly forgot.

Don't forget all the times that after you make all these calculations,
that you forget what it was halfway down the final approach course.

My handheld GPS is far more accurate and reliable than your Radio
Shack stopwatch.

Are you sure? I've got 20-year old watches that still work fine, and I've
had plenty of electronic gadgets that didn't make it past a couple of years.
Simple (Radio Shack stopwatch) is often better.

And cost doesn't imply accuracy, either. My 70-quid Accurist watch keeps
better time than my Breitling Navitimer!
