For keyboarding (in the piano/organ sense) the weakest finger is not
the fifth/pinky but the fourth.
Because for the fifth you will notice that the natural movement is to
stiffen the finger and then use a slight outward arm-swing; for thumb,
index and middle, they of course have their own strength.

The fourth has neither advantage.  IOW qwerty is not so bad as it
could have been if it were qewrty (or asd was sad)
