[racket] Style guide and inner definitions

in section 3.2 recommends to use functions below 66 lines.

But usually fuinctions are like this:

(define (process-elements elements)
     ....
     (define (process-one ...) ...)
     (define (check-element ...) ...))

 So, 66 lines limit should be applied to whole process-elements with all inner functions or to main body of process-elemets and to every process-one, check-element (in this case total length of process-elements would be 198 lines)?
