Brake Factor of supermunter on 3.2mm (1/8") Amsteel is > 40

This was an Attache carabiner (old style); the brake factor varies with biner.

I used dumbbells attached to the “brake hand strand,” starting with 15 lbs and stepping gradually down to 2lb. The 2lb slipped a little, the 3lb did not slip at all.  The line is slightly bent in the photo, but I still didn’t budge when I leaned to get it straight down. I weighed between 144 and 146 lbs with my clothes and harness at this time, so the brake factor would be calculated as >144/3 = 48.
