Siwy's right: Thuggee used gravity 400 then changed to 800. Also he used a female skin because it is lighter than male skin. In the middle of the jump he changed to male skin and moved down. And btw watch thuggees emotions during the jump: before doubling he closed his eyes so his player was out of mind and did nonsense thing. AFter that thuggee opened his eyes and realised what is happening and he just made his player move down. Siwy is right!
