<<what are you making the strings level with? The floor? The
keybed? The sloping Capo bar? The
gravitational pull of the earth?

Exactly. That's why I think the bubble is not really
necessary. You never know if the plane of the strings (which,
as has been said, can differ from agraffe to agraffe) is level
or parallel to the floor or the earth or what. And if the
middle string is high, the level could rock left or right,
giving a false indication; and if the middle string is low, the
bubble will still show level. You don't need the bubble to see
a gap between the device and the string.
