To answer Mike's question, EITHER or BOTH, depending on the circumstances and timing. :)
There is no set answer to this question, but I would more often lean more towards NOT hunting a spot "hard".
Each stand location's circumstance is somewhat different, as is whether you're mainly focused on older deer (4 1/2 or older), or mainly focused on younger deer (3 1/2 or younger). The focus on older vs. younger can result in the most ideal tactics being akin to pursuing two entirely different species of animals.
Older deer quickly gravitate to the areas they are least disturbed, especially during certain times of the day. While hunting, our entry & exit routes greatly influence where deer will relocate daytime bedding areas. They will often position themselves where they can either see, hear, or smell our comings & goings (without our realizing they're bedding nearby monitoring our activities).
This means they will often position themselves remarkably close (commonly 150-200 yards) but either perpendicular to the human activities directions of travel, or say behind a parking spot, behind a house, etc. What they typically do not do is expose themselves to a frequent (or even infrequent) line of travel (comings & goings) of hunters whereby those hunters would detect the deer's presence.
It's much easier than most would think to "overhunt" a spot, which I'd commonly describe as a 250-yd radius of a stand location, as well as the routes taken to and from that stand. You can typically get away with the most hunting a spot during the rut. You will typically get away with the least before the rut, such as during the October archery season. For this reason, many mature deer hunters don't want to much archery hunting in their best spots, instead waiting until conditions are more favorable to success.
Personally, I like to hunt a different spot on an almost daily basis, although I frequently am only a couple hundred yards tomorrow from where I was on stand the day before. Will typically have an entirely different entry/exit route to two "spots" close to each other. I like to focus much of my hunting around the perimeter of the areas as much as possible, leaving the interior less disturbed.
Rule of Thumb 1:
The less "disturbed" the deer, the more they move around during daylight.
Rule of Thumb 2:
The deer very quickly gravitate to those areas within their range where they are least disturbed during those hours of either day or night.
This can mean deer will often spend their day bedded in an "undisturbed" spot over a mile away from the fields they may feed in at night.
The more hunting around those fields, the farther the deer bed away from them, and the later after dark before they come towards them.
