Hello!

The Ageton Classic is not a derivitive of the the Ageton Pub 211 short table so is not subject to the errors you mention. The Ageton Classic method simply substitutes the Ageton Pub 211 log cosecant (A) and log secant (B) for log sine and log cosine when performing sight reduction using the law of cosine formulae. The Ageton Pub 211 method splits the navigational triagle into two right triangles. The Ageton Classic does not.
I wish someone knowledgeable would finish the SR article on wikipedia - making an overview with all the strengths and weaknesses of the SR methods in existence.
Thank you in advance.

Tony
