It might be a "useless" suggestion for you, but it might be helpful for others who have a short stroking setup or have a nozzle thats very sticky with the hop up. I currently use a stronger spring and I experienced NO loss in FPS or gas efficiency. I can shoot between 45-50 rounds per filled magazine.

Well obviosuly the nozzle being stuck "in battery" is normal, no one has refute this concept. This is required for the next round to chamber. In fact, the purpose I use a stronger nozzle return spring is to assist the RETURN of the nozzle spring back to battery faster during the blowback cycle. StrikeFreedom did not comment on nozzle being stuck "in battery" is normal. He only indicated how the magazine pushes up the air nozzle to facilitate its seal with the hop up. He noted that it is a "bonus" because it helps to form a better air seal, he did not mention how the nozzle being stuck "in battery" in normal operation.

EDIT: the air seal between the hop bucking and the nozzle head would decrease as well since a stronger return spring will reduce the effect of any friction holding the hop bucking and the nozzle head together when the gun is fired. You'll probably see a gas plume (or a bigger gas plume if you already have it in a stock gun) coming out of the ejection port; which is wasted gas.

How will additional energy be required? Before the gun is fired, the air nozzle sits snuggly within the hop up chamber. The air nozzle spring, regardless of its strength, does not do anything at this point since it is not compressed. Moreover, the air nozzle spring does not affect the "friction holding between the hop bucking and nozzle". When the gun is fired, all the gas is initially directed forward to propel the bb which is independent on the nozzle return spring. Only once when the floating valve shuts, does the gas direct backwards to the rear of the air nozzle pushing the slide backwards. At this point NO gas is directed forward since the floating valve is shut. The blowback (i.e. slide moving rearwards) continues regardless of the air nozzle spring. The air nozzle spring only helps to return the air nozzle to battery.

Not true. If your nozzle is very sticky, like the SD POM I had, it will NOT return back to its original position. For people who short stroked their gun and if the nozzle is also sticky (possible cause can be swelling of the hop up), the nozzle may also not return to battery or as you suggested in its "original position."
