why would you specify the value of any component to a couple of significant digits when the tolerance is 5%?
Tolerance means here you will never find a capacitor which is larger than 5.292uF and smaller than 4.788uF, that's all it says. If that matters, it's not the manufacturer to decide.

In CRT television, critical values are nessesary for deflection systems to make sure the picture fits the screen accurately.
Too big of a cap, even in tenths of a percent, can make the picture stretch past the screen.
Why introduce unnecessary round-off errors? If you have to have a non-standard value because the standard values are too far off, you might as well specify the value you like to have. It certainly does look unusual, though.
Yes, for projects that I publish on diyAudio, I tend to choose Zetex transistors because they are seldom counterfeited. That reduces heartache among builders who might otherwise have purchased from sketchy websites that are flooded with counterfeit crapoleon. I also tend to specify Panasonic EEU-FR electrolytic capacitors because they have extremely low ESR...and they're not much more expensive. I want builders to wind up with really good capacitors in their "leftover parts" box. Then, sometime later when the urge to "use whatever you've got" becomes overwhelming, what they've got is actually quite excellent.
Mark,
one of the funniest posts. Bulls-eye!
