No requirement for an apology, but I think you need to take an appreciation that pilots at all levels, PPL, Imcr, IR, and ATPL, all have varying levels of competency, hence the reason that 18000 hr ATPL pilots drive perfectly serviceable and flyable aeroplanes into the ground. It happens at all levels, and I know by reading your many posts, you are highly experienced. Hence, it gets me going when you refer to ratings as , Mickey Mouse. You should appreciate that individuals have taken it upon themselves to go and get additional training, and ratings. most Imcr pilots, certainly that I know, go on and respect the rating, by taking recurrent training, and are sensible enough to understand their limitations.
The accident rate in the US, where most have instrument ratings, contain a lot of loss of control in IMC, not a huge amount here in the UK, so someting in the Imcr must be working, or, pilots do not fly as much IFR, as the States.
From my Imcr, I went on to do the FAA IR, because I wanted to, and also realised some of the IMC limitations. But it was a very valid rating, and helped me in a lot of scenarios simply because I had done it.
