"The angle of the slope of sand, depth, throw radius, gravity, moisture, particle weight, particle size, wind direction and velocity all effect dispersion patterns making it far more difficult for sand splash to escape bunkers with certain configurations."
The larger the face the steeper the angle, the larger and steeper the face the steeper the throw radius, gravity is a constant in all bunkers as far as I know, bunkers should remain dry most times, wind direction is not much of a factor inland. Another factor is the volume of sand per shot. The steeper the face the more likely a ball rest on the face or the base or plug into the face, the volume of sand throw created from those three scenarios is greater than from a conventional shot from a shallow bunker. Yes fronting bunkers would logically be effected by this alledged theory, shots rarely bury into the face of flanking bunkers.
I don't buy the sand splash theory either, if it were true to the extend some are saying some of our older bunkers would have climbed eight or ten feet.
