Adjusting non-adjustable hydraulic

On the Longchamp the engine is pretty stock. Being brought up around Chevy adjustable rockers, the non-adjustable pedestal ones seemed a mystery to me. After reading page 118 in How to Rebuild Ford V8 Engines, by Tom Monroe, I got more mystified. Because if I'm right, there's an error in the book. And normally these HP Books are pretty accurate. So help me understand.

The books says:
"Wiggle the rocker arm and rotate the pushrod to check for slack, and look at the lifter to see if its plunger has moved. Run the bolt down while keeping track of the number of turns. When the fulcrum bottoms on its stand, stop turning and counting. The range is 3/4 to 1-3/4 turns. [] If fewer turns are required, you need a shorter pushrod, and a longer if more turns are needed"

Unless I've totally misunderstood, the last sentence is wrong, I think it should read "If fewer turns are required, you need a LONGER pushrod, and a SHORTER if more turns are needed".

Anybody agree with me? Is Tom Monroe on this forum?
