Speeding tolerance in Europe

A few months ago I stumbled upon a French government site showing tolerances on speed limits which was similar to that shown above.On the N10 south of Poitiers I drive at 60mph through 90kph zones so with their tolerance and my overstated speedo I just about comply.It is easy to fall foul of their sneaky camera designs especially at night.Having said that I never exceed 110kph/70mph anyway and I always respect urban limits.However I did go through 50kph roadworks near Boulogne on the motorway at 50mph before I put my kilometre hat on.I’m waiting on that one.I’ll also be travelling on the first day of the new 80kph limit so I’ll see how that goes.
