It's quite all right to say something like "made a total mess of that one" or "had time enough to make and drink a cup of tea". If you come a bit further up the fleet then phrases like "could have done that a bit better" come in handy. Bragging is an absolute no-no: none of that American talk of ass-kicking here if you don't mind.
So I'm a bit stuck, and will simply say we were not bad three times in a row and go make myself a nice cuppa and possibly down on a Pimms or two later on.
