Do you know the trip current for the main RCD (Ramp test)? And the current board leakage, I have had a couple of houses right on the limit for the RCD, then adding something with acceptable leakage pushes it over the limit.
 
How do you mean 5 minutes to do a global? Usually takes about 20 mins for the occupier to run round and unplug everything. Then you have to spend another 10+ mins working out whats still connected......problems pretty obvious here why complicate it??

Nah leave it all plugged in, IR to earth job done. Does not more harm than a PAT, if you get problems then unplug.

Nice one, don't make a drama out of it. Problems obvious, no need to conduct an inquest, times money! Tricky concept for some folks.....

5 minutes! As above,you are looking for a fault not doing initial verification,so leave everything plugged in and you are more likely to locate the problem.
Over the years I've been to loads of jobs where a previous sparks has disconnected an 'obvious problem' only for the tripping to recur. 5 minutes testing found an issue on a completely unrelated circuit.
Your cavalier approach is a recipe for comeback.
