[Doc-SIG] Question about SequenceMatcher.quick_ratio

[INADA Naoki]

Thank you, Branodn and  Doug for quick reply!

The word "upper bound" is also used in Japan with mathematics.

That's the answer I wanted!!

I've got "This isn't defined beyond that" means
"This method is not defined in detail more than".

I've misread that "beyond" means "over the upper bound".
Maybe, "more" is easier than "beyond" for non-native English
readers.

Thank you very well.
