Post subject:  Inconsistent Flash Output from AB800

Thought I would start on the forum first before calling tech support. I have 3 AlienBee B800s and I've noticed that the flash output between shots is not consistent. Meaning the light output seems to either be higher or lower than the set amount between shots. I've attached an image of a series of 3 shots. The time difference between the shot 1 and 2 is 12 sec and shot 2 and 3 is 3 sec. This should be enough for the strobe to recharge. The strobe in question is camera left and set at 1/32 power. Notice how the camera left side of the face is darker in the second shot and still not the same in shot 3. My question is if this is a flash tube issue or something bigger?

Thanks for any help.
