To elaborate on what edge said, think of grenades for example. You throw them and then around the origin of where they land, they explode sending shrapnel into nearby targets in its blast radius. The blast radius is representative of the area of effect.
It differs on the class but think for example of say the Alchemist, where the normal targeting of Throw Bomb is centred on the principle target but without levelling the tier 2 Alchemist Protection; you realistically want to manually shift the centre of target so that you can throw your first bomb in such a way it includes both your golem and the principle enemy within the first-thrown radius of said bomb but with out hitting any friendlies. [ ..and afterwards even more-so with the various on-hit golem effects such-as the bonus granted to the golem by being within the AoE of thrown bomb radii from E.G. talents caustic golem or ice armour]
Also the tier-3 talent of Explosive Admixtures / Explosion Expert increases the damage radius [AoE] while simultaneously granting a damage bonus for limiting that same AoE [ and with a maxed talent level that damage radius is so large you'd have to target the middle of a large and very open room just to throw an unmodified +bomb].
So you'd get the ever increasing damage bonus for cutting off/containing the radius of said bomb's AoE. So manually shifting the target of the AoE is key.. if you can contain the bomb to say a 2x3 room it doesn't matter where the enemy sits within that room. It is about containing the explosion radius of the AoE rather than where the enemy happens to sit within that AoE.
[ You don't get a damage bonus just for being centred within the AoE on a target.. but from the managed effect of a contained/restrained throw bomb explosion radius that also manages to include the enemy/enemies within its AoE. So in this case there is no difference in terms of damage from the enemy sitting on absolute centre or if from just sitting on the fringes of the Throw Bomb AoE.. you get increased damage from containing say a +6 bomb radius within a smaller 2x6 room.]
P.S. ~ Do anyone know if it looks at the max +AoE radius and the tiles/squares within? So with every square that exists within a full open +6 radius max you get an ever increased damage percentage bonus just by limiting that number or does it go by levels? [ If by levels you'd get the same damage bonus from say containing the max AoE to 15 squares as you'd a 21 tile/square but within 8 tiles you'd get max +damage.] From play it feels both super loose and generous which also makes it very hard to judge.
Apparently the containment damage bonus of bombs just looks at how many spaces it is unable to hit (due to terrain) out of its maximum, and the damage bonus is not linear. It scales up to a good bonus pretty quickly, and then doesn't get much better from there.
Also, another term for the OP: PBAOE means Player-Based Area Of Effect... unless you are hungry for Peanut Butter.

A third? Max bonus and u contain ..what? It does not quite seem sequential. When does it stop getting better?
The damage scales by the log base 10 of the number of missing spaces.
So at 10 missing spaces, you get +100% damage. At 100 missing spaces, you get +200% damage. (At talent level 5, anyway.)
The bonus is divided by (6 - raw points in talent), so the difference between levels 4 and 5 is a lot bigger than the difference between levels 1 and 2.
Well, that's just the math. For the tooltip it actually figures out the theoretical maximum number of spaces it can hit based on the explosion radius, and displays that.

Sure. Max radius is 6, so the max blast area is 13x13 (169) minus 8 tiles on each corner (to give it a round shape rather than a square), so theoretically you can hit up to 169 - 4x8 = 137 critters with a single bomb.
