Im not a big fan on statistical proof and averages. that .35% (or whatever) that fail the 3sigma rating has to be out there. When I think about that and I look at my cams, I figure it raises to 50% - either its a good cam or its a bad cam.

millions to one happen all the time. We call it being lucky or unlucky. Like last week I found $5 in a drain at uni, normally I wouldnt look down at all, but to look down AND find 5 bucks is pretty damn lucky. That sucker bought me two coffees that day. Ive looked again every day since - and I doubt it would happen again. Million to one (or maybe 99.85% it wont happen)

Or if you put half your body in the freezer, half your body in an oven. Then average it out. dont worry cause your fine.

For me, companies spraying about sigma3, is like them saying "dont worry, almost all our cams are good. Almost..." or "hey guys, .15% of our products are faulty, but we are not going to tell you which ones. Its a lucky dip. 0.15 may not seem a lot but concidering how many we make and how many countries we are sold in...good luck."

My point is a statistical formula like sigma ratings isnt going to fix a cam thats broke, nor will it point out the broken ones. You should be checking all your gear and never put blind faith in anything.

Me, I still use my aliens cause Ive had the (mis?)fortune to test them on several occasions. Though I concede I wouldnt buy any new ones.
