I have no idea what your talking about here. It takes the same number of
activities to create an A with both the dual lever and single lever paddles.
When using a dual lever paddle I hit the dot lever with my thumb. Once
contact is made with the dash post, I release it before hitting the dash
lever with my finger. Once contact has been made on the dash side, I
release that lever. This results in four activities, push release, push
release,or, as you call them, DOT, dot, DASH, dash.
With a single lever paddle the same amount of activity is required. Your
thumb pushes the lever over to the dot side. Once contact is made you
release (the pressure your thumb is exerting on the finger pad) and your
finger then exerts pressure on the other finger pad to push the lever over
to the dash side. Once contact is made on the dash side you release the
lever. This results in four activities, push release, push release, or as
you call them, DOT dot DASH dash.
You claim that your finger and thumb operate in unison. Do you move your
thumb backwards as your pressing the lever with your finger? Do you move
your finger backward while your pressing the lever with your thumb? Are
both the thumb and finger resting on the pads at the same time? If this is
true, then I would think that you would have to exert more pressure on the
pad to get it moving in order to overcome the force exerted by the opposite
digit. Hmmmm! This could explain why single lever paddle users tend to hit
the paddle hard.

When using a single lever paddle you must release the lever from the dot
side before it will move to the dash side. You can not escape doing this.
So using a bug or single lever paddle requires DOT dot Dash dash (4) If
you don't release the dot contacts, how are you going to move the paddle
over to the dash side?
When creating an A, the dual lever paddle activities are the same as the
single lever paddle. DOT dot DASH dash. (If I keep the dot contacts closed
while closing the dash contacts, a dot will follow the dash and the letter
R will be sent. I must release the dot contact before closing the dash
contact.)
As someone mentioned earlier, Stan, W9WBL, provides an option for his V22
dual lever paddle to allow the user to use it like a single lever paddle.
Think very hard about this Mike. What your saying is when used as a single
lever paddle the V22 becomes more efficient.

I agree with you here. Just send good code and I will enjoy copying it.

Mike it sounds like your defining 'better' as meaning 'easier'. Over the
years I've found that using my dual lever paddle is easier than using my
bug. Over the years of using a dual lever paddle I've lost my bug skills.
As a result it is easier for me to use the paddle than it is to use the bug.

It is more efficient! But that doesn't mean you have to like it. My VW
Jetta TDI Diesel is most efficient running at 55 MPH but I rarely drive at
that speed. :-)
