Andres,
I think you’ll find that you can significantly extend your glide by pulling the prop
RPM control out to coarse pitch…if needed. I’m not recommending this as a “standard landing technique,” but it’s very useful in an emergency situation (e.g. real engine out). In fact, the prop control can be used like the throttle to modulate descent rate
once you have the landing area nailed…just move it gently so as to allow the prop governor to keep up and not “overshoot” the RPMs. (Of course, you’ll need engine oil pressure--wind milling engine--to do this.

Just came back from flying the IV P, early slow built heavy 2650 lbs, 91 degrees oat 40 gallons on airport altitude 460 feet 1500 foot pattern 120 kts on power off on the break (initial
for those non military) break at the numbers prop fine pitch 35 degree bank landing gear down on the break flaps on turn to final I guess I should do a itube for those that say its not possible wingtips no stall devices
Practice, practice, practice

Ditto for me in my IV-P, although I do fly 1000’ pattern altitude. I expect some would object to a low-wing airplane coming down on top of a high-wing by flying
a higher pattern. My only defense is that I am aware of the risk, and check especially carefully for this. I also recognize that I am most likely to hit someone in the tail, rather than vice-versa, so I consider myself “the burdened party” to see and avoid.
For those of you who have not practiced engine-out landings to a full stop, I encourage you to get a QUALIFIED instructor or experienced Lancair co-pilot and
practice this at a suitable runway. (3,000’ is not suitable for practice, just in case this is not obvious to all…

Maybe I’m just a lucky guy but I regularly practice power off approaches from 800 ft AGL on downwind abeam the numbers in both our
320 and our IV. It CAN be done safely and consistently. Training and practice are the keys.

Robert,
You should try it under conditions that are more likely to be the case.
Descend to pattern altitude, 1000 ft AGL, slow to pattern speed, and idle the engine abeam the numbers and see if you can make it
I recommend you idle the engine and not kill it, because I would be surprised if you do make it. I also don’t recommend you coarse pitch the prop since you may
need to add power for the go around.
