I did not note any topic on this: in what order should the luggage scanners be arranged. I tried the 2 following options, but did not really noted a difference.
Probably, more seasoned player will have an opinion :0)
Every luggage pass trough all Lvl1 and 2 scanners in line, and any rejected by any of the 6 scanners goes to Lvl 3 manual check. This option is to me more logical… but I might be wrong :0)
Every luggage passe throug Lvl 1 scanner, only rejected ones pass at the next Lvl 2 scanner, rejected to the next, etc.
This option seems to me less logical.
Well, what is your take, mates ?
