I don't think you're reading the your stretch chart correctly or it's wrong.
Here's an other reference from the
McGraw-Hill Boating Encyclopedia:
"Nylon is a synthetic plastic that was marketed after World War II. In fiber form, its stretchability makes it particularly suitable for anchor rodes, mooring lines, and dinghy painters. Under a 20 percent load, nylon has a working elasticity of about 22 percent, or more than a fifth of its length. This compares with a stretch of about 9 percent in Dacron, another synthetic plastic fiber. Nylon’s high stretch enables it to absorb the shocks a boat generates while at anchor— shocks that would otherwise part the line, unseat the anchor, or damage deck cleats or mooring bitts."
