Buckstones:
The AA route planner times and distances given indicate an average of 58 mph direct and 55.6 via Scotch Corner. Obviously these are based on car timings, would you add 50% for trucks or some other factor?
With DD999’s limiter you could probably take at least 25% off those times…and if the ‘must catch the boat’ button is engaged it’ll be at least another -10%…
