Understand what you are saying, but here we are documenting what POV-Ray 
is setting as the default if the language level seen by the parser is >= 
3.5. This override happens on seeing the media keyword. A user can, for 
example, still specify method 2 in that media and then knowing that 
default max value is 10 matters.

Aside: I'm with you in not understanding why the parser sets the max 
value for language level >= 3.5 for method 3, but it does. If it didn't 
we'd need to leave Max 1 for the same reason - it helps users understand 
what defaults are when those defaults apply to the method they are using.
