I remember at one a few years ago the slt said that by the end of the first day the suits had found out everything the slt had hoped they wouldn't...
It's different now of course. You can hide odds and sods and, of course, all the over preparation/suit wearing/whizzy lesson pull out is a bit bollocks. So, yes, the system's fucked and there's prolly a huge waste in terms of inspection budgets. But I doubt anyone's going to try to change it all that much.
