Steve did a huge trawl of all routes attracting AAA points last year, so most of them are now faithful to audax regulations.
Steve does take routes on trust if there is no tracklog or the like to contour count. However if the route is over/understated, he'll amend it once he gets something he can check. The Coasts and Quantocks event got its AAA points reduced from 2 to 0.25, after the event had taken place.
