Two years ago using Knuckles & the Big Bang on lap 2. Another gravity luck attack form extension move before the last turn. Might still have a better result though.

Sonic & the Big Bang, the 2 gravity increase items did it again on lap 1 for me. Instead of grabbing two gravity items ( 30 ) in a row, I aided meteor bursts and grabbed one. Saved on my memory card, so it exists.

Shadow & the Big Bang, I never expected a lap like this, I meteor bursted the containers a lot better this time, and got the 30 gravity points item. I was ecstatic when I got it. Proof: this lap record is saved on my memory card.
