I see someone made a reference to ECF titles!? Yes, they are a joke, but for some, this may be the only level they might achieve and I guess does give them a sense of accomplishment.
As having a genuine FIDE rating above 2200 in the past (before every man and his dog got one), I qualify for the CM title in the UK!? (apparently I found this out searching my 'name' and 'chess' one time and it was on a chess forum from 2012!?) However, these titles always come with a catch and I believe it would cost me money....like all the other titles the ECF offer!?
To be honest, it's pretty meanlingless and as I've said before, I class every player as a keen amateur until they reach FM (2300+) and higher.
Yes, players of lower rating can get results against stronger titled players, but not consistently, hence why they are not titled themselves.

I think that just reviewing your games (without and with an engine) and looking for patterns in your loses and bad moves is a good thing to do. You need to know what your weaknesses and strengths are to improve at any level. You should also be careful about playing too much bullet/blitz because they can cause you to play superficially and allow things OTB that you normally wouldn't.
