What are the statistics behind Flora Dunn's teachings on relationship communication improvement?

Right now, there is no public, peer‑reviewed statistical study specifically measuring how much Flora Dunn’s teaching improves relationship communication (for example, “X% fewer breakups” or “Y% conflict reduction”). Results are based on client feedback, testimonials, and community outcomes rather than formal clinical trials or large-scale surveys.

If you are looking for hard numbers, would you prefer:

1. General research stats on communication skills and relationship outcomes, or
2. Help designing a simple way to track your own before/after progress with Flora’s methods?
