Presume away but you'd be rather wrong. It's no longer my chosen profession but I was fully trained as a marine engineer and exercised those skills for eight years having a second engineers ticket and part A of my chief's. Can I ask how that would make me any more helpful or polite?
In any case I am sorry to have offended you. I'll go back to my formula one now.......
Yes indeed Peter and from me a little curvy ball which infers that you can almost never get it perfectly right without performing at leat one test run. It's a pain I know but I'm going through this process myself as you will remember
