After reading that Service Letter I do what I need to clear the ground and once all obstacles are cleared I climb at just above 5200, which tends to give me about 82 knots and 800 - 1000 FPM (solo).
If you set the blade pitch to get the 5200+ rpm at 75 knots (Vy), on take-off, you will easily hit 5800 rpm at WOT in level flight. The recommendation is not practical. A setting that gives you 5050-5100 rpm seems more practical.
