Boy, considering the last time I submitted a score for this game was in like 2011 or 2012, this has come at a time way past my unleashed prime. Anyway, I should still have this stat saved on my Xbox which I'll get around to, no guarantees it'll be that soon because I have to retrieve the copy from my friends house.
I used to talk about this in TSC chat, and if I had the logs (Maybe Groudon could help me out here) and I used to talk about my stats whenever I obtained a record in there, and I explained pretty much what I did and that my score was a lot higher than everything else.
Can't say I remember exactly what I did but I'll be trying to replicate it as best I can if the stat is still saved and I'll record it. All I know FOR SURE is, I definitely didn't use the ramp abuse trick and I abused all the checkpoints. Couldn't have asked me for a more annoying score attack, either, haha.
