No one is playing games, the door handle is too proud of the other parts and who falls unconscious laying perfectly straight of their side?
Sorry Zoso,but the video makes everything very clear.The handle is proud and this is the reason that all three points of the Aga are touching a curved back,the three points form a curve with the middle point furthest in,CONCAVE to the handle and the other point.
In other words we have three points of the Aga forming a curve touching a curved back/spine.Very simple.
Watch the part where the volunteer lays down,you will see the curve that the parts form against his back and Boyce comenting that they are all touching.
As for lying completely parallel to the marks,we cannot tell if this is the case,the marks are only a couple of inches long not the complete length of his back,so there is no way of knowing how parallel they are in that short distance.
No,everything is quite clear and in order Zoso.
