Primary (Petral) is on my left (It's a camera thing... right hand is always gripping camera so to look at computer, means maneuvering a beast of a camera), bottom timer on right.
With the computer on the left, how do you keep from waving your primary light around when you need to look at it?
Not an issue if the computer has an illuminated screen, like a Shearwater.
I think that Ron meant that if you are holding your can lighthead on your left hand with a Goodman handle (as you typically do), when you turn your wrist to look at the screen, you are going to be blinding someone. Not as much of an issue on OC, since you mainly look at your computer on ascent, when your light is likely to be clipped off.

Is that a real thing? People being blinded because you move your arm a few inches to look at the computer? That seems like a bit of a stretch...
To me the right arm is just practical because I can see it when doing buoyancy stuff. Before illuminated screens it needed to be on the right so you could light it up with your left hand when riding a scooter. But the buoyancy thing is the biggest driver in my mind.
It's not really a stretch at all. And while I'm not a cave diver, watching where your beam goes is pretty standard courtesy for anyone using an extremely bright can light. Same reason why some people rig a bungee loop around the cable behind the lighthead in addition to the bolt snap on the Goldman handle. It gives you the option of clipping off a light that is switched on so that it will hang down at the floor, if you need two hands but don't want to blind someone.
It has nothing to do with inches (lateral motion), it has to do with angles. Try it right now and you will see. Can light is on top of your left hand, pointing forward into the darkness of the cave or the wreck. Now turn your hand like you are checking your watch and see where the light is pointing. That 3500 lumen light cannon has now turned almost 180 degrees and is pointing straight over your right shoulder. Where there might very well be another diver.
