So far me and my friend have been dominating the leader boards for the "parkour this" challenge on ps3. We've been finding new pathways to shave our time and get more points, but we've only gotten maybe a few thousand more points than before.

Now some guy has completely blown our scores out of the water.

Our scores were around 125000+ or so, which we thought was almost near the limit.
This new guy got over 144000. I don't understand. Is there really a route fast enough? I've only seen scores up to 130,000+.

Post any strategies you know that he may have used to get so many points.

He could be hacking or it could be that he's found a better route. Have you tried waling on the fences?
