OK, Mariner9, I understand your viewpoint but I believe cost should be kept to an absolute minimum at all cost.
If the examiner is taking the view this is a failure, the moment the second phase of the test is started and the candidate has failed to recognise his/her egregiousness, he/she should be told the test is failed and given the option to fart around with a SPIC flight or put money saved towards another test.
Whether the purists like it or not, I believe that the game is to get the ticket and carry on with the learning in a more relaxed environment. This does not mean reducing your own very high standards but if you live in 'perfect world' nobody would ever pass the event! We would all fall foul of self criticism irrespective of the examiner's expert witness.
