If it was your job to count 10 widgets and press a button when you'd counted 10 widgets, would it be right to press the button when you'd counted 9 widgets or 11 widgets?
That's an invalid analogy.
What if the job was to count the widgets in each box, and that number was supposed to be 10.
If you're given a box with 9 or 11 widgets in, is that your fault?
Are you unable to say "my counting was accurate" because somebody else put the wrong number in?
Would 'I persistently turned up for work on time to the best of my knowledge' cut it with HR?
Do you have the skills and the equipment needed to determine if you were turning up on time? If yes, and you weren't then you're lying, and this discussion isn't about people falsifying reports.
If no then maybe your competence to determine if you were turning up on time should be questioned, and this discussion is not about people who aren't competent to sign EICs.
If it's your job to be the inspector, then inspect. Don't put your feet up because it's a rainy day and a muddy site and justify it by saying that you inspected and tested to the 'best' of your knowledge.
And where on earth have I suggested that?
What inventions are you adding to the words of mine that you have read which lead you to think that's what I'm suggesting? If it's your job to be the inspector then you would know that staying in the warm and dry and not inspecting is not in accordance with BS 7671, so it would be a falsehood for you to say that to the best of your knowledge and belief your inspecting was in accordance, and this discussion is not about people falsifying reports.
If it's your job to be the inspector, then inspect.
And report what you find as a result of your inspection.
If you are
unable to carry out a particular inspection, then record that fact.
It's pretty clear what the BS7671 standard forms require (I would have thought).
