I recently started some research on the this topic and am crossposting it here from my initial thread on the PC (http://forum.gsplayers.com/showthread.php?96550-Research-The-Effects-of-Creature-Height-on-Melee-Aiming). I welcome your thoughts or data.

I've gathered only a few data points but my very super preliminary research seems to indicate that creature height by position is as follows:

Height of ASSESS {creature}:

Position	Height Modifier
Standing	1.00
Kneeling	Round(Standing Height * 0.60)
Sitting	Round(Standing Height * 0.45)
Prone	Round(Standing Height * 0.10)

Data:

The lesser minotaur is medium in size and about seven feet high in his current state.

The lesser minotaur is medium in size and about four feet high in his current kneeling state.

The lesser minotaur is medium in size and about three feet high in his current sitting state.

The lesser minotaur is medium in size and about one foot high in his current prone state.

The minotaur warrior is medium in size and about eight feet high in his current state.

The minotaur warrior is medium in size and about five feet high in his current kneeling state.

The minotaur warrior is medium in size and about four feet high in his current sitting state.

The minotaur warrior is medium in size and about one foot high in his current prone state.

The Illoke mystic is huge in size and about twenty-two feet high in his current state.

The Illoke mystic is huge in size and about thirteen feet high in his current kneeling state.

The Illoke mystic is huge in size and about ten feet high in his current sitting state.

The Illoke mystic is huge in size and about two feet high in his current prone state.

Why This Matters:
I want to increase my combat efficiency by aiming at vital locations without "setting up" the creature, if possible.

(1) My character is a Human, which I assume translates to 6 feet. [I]How can I verify this?[/I]
(2) Given (1), wield a morning star.
(3) Given (1) and (2), I am [B]able[/B] to aim at the [B]head[/B] of an [B]8 foot[/B] creature.
(4) Given (1) and (2), I am [B]unable[/B] to aim at the [B]head[/B] of a [B]9 foot[/B] creature.
(5) Given (1) and (2), I am [B]able[/B] to aim at the [B]neck[/B] of a [B]9 foot[/B] creature.
(6) Assume the head of the creature is equal to the height of the creature in its current position.
(7) Assume the neck of the creature is equal to the height of the creature * 0.90, rounded.
(8) Given (3), (4), (5), (6), and (7), the difference between (creature_height - location_height_modifier) - (player_height + weapon_height_modifier) must be equal to or less than 2 to allow aimed strikes. Alternatively, if the morning star has a weapon_height_modifier of 2, then the difference must be less than or equal to 0.

Confounding Variables:
(1) Specific weapons, more than likely, affect the ability to reach taller creatures (e.g., lance).
(2) What are the standardized racial heights? How do we determine this?
(3) the location_height_modifier is more than likely percentage based. I assume Head = 1.00; Neck = 0.90 for bipedal creatures?

I would like to hear your thoughts and more data points, if possible. This is something that's always bothered me about playing a "shorter" race, but the degree to which it actually affects combat efficiency is unknown.
