You mean "factor 1.78 falls" and "over a 10mm diameter (simulate a carabiner)" , don't you :-)
pedantic, I know, but there are edges and there are edges :-)
the "sharp edge test" which some ropes claim to meet is over a 90 degree, 0.75mm radius edge, and the rope must survive one standard drop test |
