The numbers I use for spacing and pressure for all of my keys, single
lever paddle, dual lever paddle and straight keys are as follows.
Contact spacing is adjusted with an automotive type or machinist type
feeler gauge to .005" or 0.13mm
The pressure to close the contact, measured at the tip of the level is
20 to 30 grams measure with a push type spring scale.
All of my keys are adjusted accordingly. Thus changing from one to
another is not an issue.

I initially had a similar problem - KXPD2 failing to key dahs properly/reliably. The main reason
was the contact spacing was too close. I like a light touch and close spacing. I spent quite a bit
of time adjusting the pivot pin play using the small allen wrench provided. You want them tight
enough to not allow the paddle to "wobble" but not so tight that it binds. Once those
adjustments are made, set the contact spacing where you like it but wide enough for the
"swing" needed to make reliable contact. You can also use a small strip of stiff paper
slid between the contacts to clear out any dust or corrosion.
