    Ok. I messed up on the T3 scale. I just looked at the left hand end of the scale and thought it duplicated the ST scale. It doesn’t.

    Ignoring the overlap, the T3 scale on the left hand end is actually 5.7 degrees (with the complement of 84.3 something. But the T3 scale decreases to the right. At first glance, it looks like you read the values on the 1/x scale. But I can’t make T3 match either the 1/x or the D scale over its entire length. The complement of the listed angles don’t seem to match either.

    I don’t understand the T3 scale.
    Regards, Noell
