Good luck!

But here's the thing:

There comes a point in your abilities where it's smarter to stop barrel rolling because the extra points compete directly against your own survival. I typically max out on BRs until maybe Zone 27 when Super Phantom starts. Then I do one BR per lap until Mach 1. Then I do maybe two BRs every three laps for the rest of the game. But once I have a hard time getting two consecutive perfect zones, I tend to stop BRs completely (usually after Zone 110). So I'll often have maybe 80 ship energy or so at about Zone 110 and then whether I keep doing BRs depends on how many perfect zones I get afterwards. I usually have these markers:

100,000 points at Zone 28
200,000 points at Zone 54-56
300,000 points at Zone 80-85
350,000 points at Zone 100
400,000 points at Zone 115-125

There comes a point on Syncopia, however, when BRs can screw you up because of the weird camera angles and possibly landing off the track! So be careful!
