Achievement Unlocked: Double-Digit Footnotes on Page 1

It is a little-known fact that the notation for the 10th footnote of a single page using the *, †, etc. convention is in fact "§§".

Yes, that's right, I actually got to the 10th footnote on p. 1 of a journal that uses that notation. If that doesn't deserve an "Achievement Unlocked!" when using this particular convention for footnotes, then I don't know what does.

It appears, however, that the journal in question (Quantitative Finance) seems to be using a nontraditional version of this typographic convention.
