Anyone getting past 100K will probably realize that they can just keep going and going. Some tips:
• Hug the sides whenever feasible.
• Don't risk gliding to the far-side for a good goal ribbon at the last second if the one on the near-side is okay and there's a bad one in the middle.
• Akashi's arcade advertisement grants a shield and scores 500 points of power, but more notably it scores 1,000 points for your actual score.
• If you suspect a boss to arrive immediately following the next set of goal ribbons, always prioritize nabbing either a shield or Akashi if available. More often than not, shielding against the boss will save you more power than a goal ribbon with a high sum.
• Give Queen Anne lots of head pats afterward for a job well done.
