This reminds me of an old joke;
Two people in a pub disscussing their work and one of them is an engineer who designs aircraft and says that he has to work to tolerances of 1/1000 of a milimetre. The second person who is a flagger for the council says "You'd be no good in my job my flags have to be perfect".
Piotr, I've had a little play with one of your Whiscombes and I must admit that it was sublime.
