Guidelines for chess tournament prize distribution Does FIDE or any national organization offer any guidelines on prize distribution for chess tournaments?

Are there specific patterns on how top-heavy the payout should be, or the balance between place and class prizes which have wide adoption?
The US Chess Federation Official Rules of Chess 5th Edition has a section (section 33, if you have a copy) that has some guidelines about prizes.  These are specifically described as recommendations and not rules.

A ratio of 10 to 1 between the top prize and the entry fee for serious tournaments is suggested (and perhaps even more if you want to attract top players.)

It suggests that class prizes be at least the amount of the entry fee, and also suggests that the place prizes all be higher than the class prizes.
