Regulated vs unregulated

Depends on purpose. For supreme accuracy and precision, REGULATED.
For brute force, UNREGULATED.
My paper punchers and pest guns are REGULATED for accuracy.
For killing coyotes, my Condor is purposely UNREGULATED.
Tally HO!

Being regulated doesn’t really have much to do with accuracy then? How much extreme spread is enough to change poi?

Being regulated makes the gun more "consistent" not more "accurate"
If a gun is regulated you will hit your target more consistently, especially at longer distances where the drop or rise in velocity will be more pronounced for an unregulated gun.
As far a how much extreme spread is enough to change POI, any extreme spread can change POI. The difference will generally be hard to notice at shorter distance, say 25 yards, but it will be more pronounced the further away your target is.

It depends on how efficient the guns' valve is. There are some guns that maintain a low extreme spread over many shots.

First of all, let's define terms:
Accuracy is a measure of a gun/ammo combination that can hit a designated point, like a bulls eye on a target.
Precision is a measure of a gun/ammo combination that can hit the same spot time after time.
Airgun reviewers shoot for groups to demonstrate precision. They don't care where the pellet lands, only that each pellet lands precisely upon the previous ones. Stacking one on top of the other. THEN they adjust their sights for accuracy; move that tight little group onto a bulls eye.
Regulators assure precision. Regulators assure consistent velocities shot after shot. All other factors being equal, this consistency results in the greatest precision pellet upon pellet, shot after shot.
To answer your second question depends on the weight of your projectile and the distance you are shooting it. You'll learn all about that through experience. For close in work, you can tolerate a lot more ES before the POI changes. For distance, ES becomes very important for all pellet weights.
Remember, all projectiles begin to succumb to the forces of gravity the moment they leave the barrel. They fall at the acceleration rate of 33 feet per second per second. That rate of vertical acceleration is constant until it reaches terminal vertical velocity (maximum free fall speed). For a human jumping out of an airplane without a parachute, the terminal velocity as about 120 mph. When he leaves the airplane, his vertical velocity is zero and quickly accelerates at the rate of 33 feet per second per second until he reaches terminal velocity of 120 mph. From that point he continues to fall at 120 mph for thousands of feet until he opens his shoot of hits the ground. The apparent (not actual) drop of a projectile seems less at muzzle velocities. But as velocity slows with distance, the apparent drop seems higher. Horizontal velocity gradually gives way to vertical velocity. The more consistent the forward velocity, the more consistent the apparent drop at a given distance. Regulators maintain the most consistent velocity shot to shot. And since the vertical rate of drop is consistent and fixed, the point of impact is likewise consistent with a regulator.
In summation: maintain precise velocity, you hit the same hole time after time, all other factors being equal. Regulators are designed to maintain precise velocity; whatever velocity that you set it for.

A small tit but...
From BeenamR7 "Regulators assure consistent velocities shot after shot". A regulator is by no means a magical nor perfect device and while a regulator will more precisely control the air pressure used to accelerate the projectile and therefor increase precision, variations in pressure will exist.
Additionally, there are many other variables with must also be understood and reduced to truly gain precision. Make no mistake a regulator is a huge first step to creating a precision air rifle, but its only the first step.
