Good luck with the thankless task of rankings. Only as good as the info supplied and riddled with whingers complaining when they have contributed little or nothing. However, I don't mean to put a downer on it. It's a dirty job..........

However, back to Lee's point.
Initials are used for many different reasons, rarely with any consistency.
You mention John orchard and Csw. At this time I believed that he was the best full contact middleweight in the country. But we were out on a limb on the coast and things were not as spread out as they are now.
We were going into others back yards and winning contests that we were not expected to which made things even harder. We chased one particular fighter who was British champ but he had his sights on world honours and so it went on.

With a dangerous reputation and lack of profile we were stuck in a rut, so the only thing to do at the time was get him in the mix with a 'world title belt' . Worthless in itself but a platform that paved the way. That and the portfolio of opponents that was gathering. From there it became easier to pitch him with the bigger orgs, or actually as it turned out - the bigger fights, with or without a belt.
If we used the criteria of some of the current world champs I.e not stepping in the ring without a new belt on the line, Orchard would probably be a 30 times world champion.

So, before I bore the shit out of you with a trip to past glory, the initials facilitate the plan.
However enthusiastic anyone is about any set of initials, they suit a cause for as long as they do - and then they don't. The people that talked about one set of initials last year, are talking about a different set this year. This years saviours will be next years destroyers. Ukmf being a good example. People conveniently blame the org usually, but the reality is everyone is to blame.

If you picked an org with no written rule set or structure, but who let you pick your own officials and have your own way with everything, you got what you deserved. If you picked one with a decent criteria but that criteria became too restrictive when they would not approve Johnny big bollocks for a title, that's the price you paid for doing the job properly.
When, on the back of this , you move away from orgs and start 'branding' with no real plan except autonomy, you end up with the bag of shite we are sitting in now!

So, the initials are only as good as the fight. The org has to make as many of those as credible as they can, although I totally accept that there are many reasons why certain fights never happen.

Sorry , early morning active mind - too much waffle......
