Default Audiophoolery in Panasonic Electrolytic Capacitor Application Notes

(crossposted to sci.electronics.design and rec.audio.pro)

I was looking through electrolytic capacitors for yet another
bloated-capacitor replacement for PC SMPS repair when I decided to
take a gander at the manufacturer's data (looking for the longest
rated life at the highest temperature so with luck the new ones will
last a few years), as pointed out by Digikey:

I saw some interesting-looking titles in the lower-right under
"Aluminum Electrolytic Capacitor Data Files", specifically the
"TECHNICAL GUIDE." Clicking that goes to another webpage with PDF
links:

http://industrial.panasonic.com/www-...BA0000_WW.html

Most notable is Section 7, in the file at tle link below. It all looks
reasonable and objective until it gets to Section 7.2 on audio, which
starts on the third page of the PDF file.

(here's the payload, folks):

There are only two pages on audio, but it has the highest density of
undefined/undefinable words I've ever seen in a "real" technical
document. I've never heard of "amount of deta" but I'll guess that
deta is short for detail.
