I found some more info here: http://www.outdoorlink.org/ol/files/trdocs/research-papers/Knot-and-cord-strength.pdf

It's quite interesting reading but this is the significant bit:
" How relevant is tensile strength to loop strength? If you tie it in a loop is it twice the
strength of the rated tensile strength? How much does the carabiner affect the overall
strength? The tensile strength of BW 7mm static cord is 2,600lbf. Loop strength on
carabiner diameter test pins was 4,200lbf or about 80% of double strength. It was
virtually the same percentage in BW 8mm static cord. "

So if looping cord around a carabiner means 80% of original strength, I'm not going to worry about this anymore.

Still not sure about smaller diameters though...
