Interesting article from 'Technical Topics' in a 1988 Radcom on how labour-saving paddles and bugs are.
Sending the alphabet on a straight key requires 82 contact closures.
On a bug, this is reduced to 66.
On a paddle without iambic (squeeze) keying (eg a single paddle) , we are down to 53.
On an iambic mode twin paddle, it is only 45.
In real life the benefit is not as great as this. The commonest letters in English, in order, are ETAONRISH. Morse is cunningly designed so that common letters are faster to send (except O anyway, not sure why this is?). On the other hand common prosigns (AR, VA, CT) can be sent with a single squeeze on a double paddle.
The other thing is errors - I certainbly make more of them on the paddle, and correcting an error reduces the effective speed quite a lot.
