What he said, It's something along the lines of there is a 'Maximum Score' and then every fault you get subtracts a chunk of points, and for every second/fraction of a second below the 'perfect time' which is usually set at 0 seconds (at least that's what it was in Trials HD) you get points subtracted. But basically agreeing with what don said, low faults is key, once at 0/minimum faults you can obtain, get your speed up
