What is a "short field" for a PA28-181

Keep in mind that the short field settings shorten the ground run but
generally increase the distance to clear a 50' obstical.

Mmm, like others have said, I would think this is model specific.
You know when you accelerate for take-off...the increase in speed
takes proportionately longer as you get faster, so you use up much
more runway getting from 55 to 60 knots than 0-5 knots (basic
physics)...thus I would think that (for instance) if you start your
climb by lifting off at 55 knots rather than at 60, you've saved a
fair bit of runway. Usually I would guess that this distance saved
more than compensates for the slight decrease in climb angle with
flaps.
