How many Flowers do I need to go up a level at 109 or chapter 22?

This answers the question if you go from 1 level to another. But it does not answer the question, how many flowers to complete a whole chapter of 5 levels or scenes?

The number of flowers vary from scene to scene and chapter to chapter. In general, the 2nd scene of each chapter requires the least, approx. 60-100, and each subsequent scene require 70-150 more than that. The start of the first scene of a new chapter requires about the same as opening the fifth scene. Usually, one chapter will require between 1300 and 1750 flowers. To be specific, level #109 requires 270 flowers. To open all 5 scenes of chapter 22, requires 1350 flowers.

Why isn't this public knowledge? It would help people strategy without have to junk up their island. Thanks for the input.
