I don't understand your problem. Things are as transparent as they could possibly be.
A few years ago, we never got to see a specific position in a merit table, never saw our club marks and just got banding updates 4 times a year (?), then the FA select those who will be promoted and, as stated in one of these posts you're concerned about, a female was promoted above a male who appeared to have a better overall banding.
Now, we see a live merit table for clubs and observers at any given point. In fact we see 4 tables. Annual marks clubs, annual marks observers, seasonal marks clubs and seasonal marks observers.
This system of having an assessment day was clearly laid out, along with how people would be chosen, at the start of the season.
