Traveller stupidity doesn't help. Couple of weeks back we even had some chap trying to use the system although he wasn't registered......
I used Iris in T3 recently, and although it only took seconds for the system to be satisfied with the picture of my eye, I had to stand for a good 10-20 seconds before it decided to let me through. So if you're reasonably adept at looking into the scanner correctly, the limiting factor does seem to be the processing time.
Plus the way the system decides which one you should look into is flawed - the poor chap in front of me had to strain on tip-toes for a minute or so before the system was happy. It's not like it would be hard for the system to allow you to use either screen, and just work out for itself which one you were looking at...
It was still faster than queueing, but for me I'd be heading for the normal queue unless there was no queue at all, or at least a significantly shorter one (as in, about an order of magnitude!)
