On Page 28 of the 6th edition, HK writes "Doing the above drill with Zero Accumulaor #3 (6-B-3-B) will show that then, all Lag Loading and Hinge Action have Angled Hinging Travel AND Rhythm. So--intentional use of Zero Accumulator #3 can be useful while unintentional use can be hazardous."

Could someone expand on these two sentences? I understand the different hinge actions, but I am in a fog as to what these two sentences mean.
