Hi Luffy
Thanks for asking that important question and I'm happy to confirm that you really did reach the right conclusion about the riders of oriental equipment , "however"
you also need to consider in your time calculations and allowances the levels of inebriation of the individual. When you consider the one step forward and one step back part of the calculation, when the level of inebriation passes level 8 , it could indeed be more than a two minute walk .
Traffic , although a minor determining factor in the calculation , it must still be considered. When we were at Harrow last month , one nite we saw two cars after 8.00pm.
Kind regards
Shoey
