1) Who cares.  The TCDS rules.  
2) What manual?  Could it refer to a different prop, or engine?

Did you get your tach checked yet?  best place to start.  Also, how's the 
compression? Do you know the prop has not been repitched?  
(check for markings under the spinner)

The range is the allowable range. Period.  Anywhere in the range is fine,
per 
the type certificate.  Climb props will yield readings nearer the top of
the 
range; cruise props near the bottom.
