I assume it isn't free, this "help", and therefore you prove the point that it is indeed hard.
Also, it seems the waiver process is about 99.99% about speaking pilot, and knowing what the FAA wants to see...But they don't tell you exactly. This is (IMHO) willfully being difficult on their part, a way to stop the avalanche and play favorites. They can't say this, of course, since that would be illegal and impolitic.
If they said, "such and such a course is required", then there would be a path, just like a regular pilot trying to move to the next level. But that isn't the way it works. The reasons may be valid and good for safety, but they are HARD to navigate for those without FAA experience.
