How to simply determine the L/D of your glider

It appears we may be close to the root of the problem. Most everyone,
myself included, use L/D and glide ratio (path) interchageably. Even
worse we often don't use the word "best" in front of it when that's
what we mean. This should be easily corrected by a suitable pentalty
for the misuse of terms. Perhaps washing out ones mounth with soap or
just ostrsizing the culpreit. When this is complete we can move on to
the other standard winter topics like contest finishes, best wax and
sealing tape.
