I accidentally submitted the same run. When i clicked submit, it was taking a bit long so i clicked it again and then i realized i accidentally submitted it twice. How can I delete the other submission?

About the golf level exploit where you grab the golf ball at the beginning and jump with it all the way to the end:

Does anybody know how to pick up speed while youre flying on the ball? Im on a controller btw. Also, does anybody know how to pick up speed on foot too, i feel like my character movement is too slow.
