Last one from me on this because you're just being obtuse.
But the
P4P does go further than the P3.
Get out of your one particular interference ridden flying spot and run some proper tests.
The range is improved. .. It goes further than the P3 and P4.
Further = improvement.
And in that environment the
P4P will go further.
An interference free location is what DJI have used to come up with the figure in the specs - not your backyard or any other location with it's own problems.
An interference free spot is the only way you can get a figure that is useful for comparison.
