I got curious about twin lead antennas for FM. I had measurements around somewhere but those included the velocity factor for the twin lead used, 0.86 or so.

I would assume that velocity factor applies to using the twin lead as a receptor element as much as it does for a transmission line. Therefor, the length given for the element should be multiplied by that factor for that particular station frequency in the article. Too long is not in of itself not going to work but it may work better if the correction is made...
