Take the 2-minute tour ×  A friend of mine has a blender with 6
control selections: One off position, and five power settings in
order of less to more power. Example below:  6 control options
A discussion has erupted over whether or not the middle power
option (3) ought to represent:  A) 50% power (The middle is
surely 50%):  enter image description here  B) 60% power (There
are 6 positions if 0% is included, there is no middle position
as such, and so assuming a linear scale):  enter image
description here  While this isn't exactly a life and death
situation, I would be interested in seeking more opinions. We
are roughly split 50/50 on what it ought to be (yes, we could
verify what it is by dismantling the blender and examining the
circuity, but no one is interested in that minor detail) :)

uniformly distributed over all the settings? –  Marjan Venema

looks like? Is the 3 in the middle or
