For me, I think the X% that indicates the coin flower (or Jellyco Missile) functions the same way as Snow Blossom. While Snow Blossom can cover 75% of the holes, Coin Flower can spawn X% from every unit passed. You can see that the game has a certain unit (that serves as a length) that can be used to measure how long. The unit can be either a block, or a hole. Every unit passed, whether or not it's a block or a hole, has a 3% chance of Coin Flower appearing.
