I could point to "... had the irregularity not occurred ..." in 12C1e(i) but that would open up a can of worms (WBF LC minutes, 2009)
You could, of course, but I do not see the relevance to this case which happened in England.

If there is no mandated pause, it is normal IMO to be a little slower than regular tempo, whatever that is.
Whether Stop card regulations are a good idea or not, what you say here is definitely not the case which creates problems. When there are no Stop card regulations, some players some times will pass like a flash. With no rules suggestion they should slow down, why should they?
Fortunately or unfortunately, depending on your point of view, Australia is the only place I know with no Stop card regulations at all.
