Profiles - How reasonable are they?

This one is for discussion with @andrejh.

We just simulated the laser labs in Isolde (508) using the workshop profile (talking 100%, light exercise) and the risk output is 7x that from an office (the old office - the new call centre) environment.

Suggest we have a discussion at some point regarding the rationality/reasonableness of these profiles, from an input and risk-output point of view.
