What is the exact definition on F speed (flap retraction speed), S speed (slat retraction speed) and VLS (lowest selectable speed)?

What is so "unprofessional" about flying above VLS but below F/S speeds, when I don't want to retract the slats/flaps?

And why doesn't the AT go below F/S speed when the speed is managed? Because it does not have any clue as to what you are about to do, retract the flaps or extend them. At S/F speed, you are usually safe to do both so it maintains it.
