Yes it does. VPS will make for a rough/bouncy landing.
Incorrect - see above.
I agree. My father has the P3P and I the P3A.
Just flying on my own I noticed that VPS caused my landing to be jumpy/bouncy. I did not like this. I turned VPS off (didn't know I could until I found it trying to find another option) and instantly noticed after that flight that my landing was far more smooth and easy going. I have to say.. the bird was a bit of a flirt at this point in time.
So I took notice in this and went on my way with my new few flights. Then when met up with my father a few days or weeks later I noticed his landing vs my landing (VPS on his, off on mine). The difference is night and day!
I'm personally not a fan of VPS. I don't think the system really works. I tried using it in the Redwood forest in CA and just following the road (paved/maintained) it did not do a very good job. I couldn't get a GPS signal and the **** bird was just all over the place as if it had a six pack of beer after doing some body shots off some hot unicorns.
