Hey tom.

These are good quesitions.

If these inputs are constant (DC), then:

Max would be +5.  Min would be ground

But let's say the 5 volt input is DC and the 2 volt input is AC (+/- 2
volts), then:

Max would be +5, min would be -2

Huh?

The maximum output won't go lower than ground.  The minimum on the
other hand works the region from ground down, so it won't go higher
than ground.  They both rest at ground (no inputs in either 1, 2, 3
and no offset). 

So if you have an input that's not crossing below ground, the Min will
rest at ground waiting.  As soon as a single or multiple cross lower
ground, then the Min will give you the lowest of those at any given
time.  

Ditto for the Max out, but in reverse.  If none of the inputs are
above ground, the Max input is at rest.  As soon as one or more are
higher than ground, the Max will give you the highest voltage of the
inputs at any given time.

THis would be screwy if the offset pot wasn't configured the way it
is.  It's just that.  At 12'o clock or therebouts (when the LED is not
lit when there's no input activity), the offset is at null - there is
no offset.  as you turn the pot CW from there, it injects positive
voltage into the mix - it raises the resting voltage up. So if you had
no inputs going higher than ground, you can offset them upward so they do.

When the offset pot is turned CCW from 12 o clock, it injexts a
negative voltage into the mix, so you can offset your inputs downward,
thus activate the min output when it would otherwise be resting.

The moral is...there's a reason for the madness of having all those pots!

hope this helps,

- P
