Carbon Fibre,
The examiners overall are very fair. The published limits are limits to use on a perfect weather day, so these are interpreted by the examiners according to the prevailing conditions.
They will not fail you if you bust one of these limits aslong as you make positive moves to correct. The only strict limit is the 250' altitude limit because this would constitute an ALT BUST which is an instant fail for that section.
In the most part you just have to try and relax, the examiners will be more than fair.
