How would you do it? (Tongue weighing)

At this point, do some real world trials. Forget about tounge weight more or less and just see how it works behind your bike. You may be pleasantly surprised.
 
"Just see how it works behind your bike"
Reminds me reading about Edison and the light bulb development. Workers were trying diligently to figure out the volume of a light bulb they were working with taking a long time and Edison said to them "Just fill the damn thing with water and measure the water."
 
TT & T
That is just what I plan on doing,
I just have to finish fitting the rear bracket to attachment to the bike.
Then I'll start loading some weights and do some riding to see the results.

Seeing that the OEM spec's are in question, I don't believe that they are valid,
and as of this date, I have received no answer to the email I sent.
Tia,
