A strand is aprox 1mm thick under load and is made up of hundreds of individual fibres.
Plain high strength steel will pull 60 kg per 1 mm circular crossection before breaking. As such 5 "strands" of steel will pull 150 kg with a safety factor of 2.
Going on your test results then the aramid is not very impressive. It is certainly no where near 10 times stronger as steel.
