good number to keep in your head for lower altitudes.

Not sure why you refer to "lower altitudes". The glide angle is
constant with altitude.

Because there's "overhead". Gliding from a higher altitude, one normally
will be able to spend a larger proportion of the glide at the optimal best
glide speed. The glide angle is only theoretically constant with altitude.
In reality, no one goes directly to best glide the instant the engine fails
and the glide angle after engine failure varies as the pilot reacts.
