Sevick appears to have been a superb engineer, but #31 material was not 
available to him. It was developed after he was actively doing any 
research. Most, if not all of his designs used low loss materials like 
Fair-Rite #61. 

Also, he seems to have keyed in largely on SWR and loss through the 
choke rather than choking Z.
