A coin-flip would have reached the same conclusion 50% of the time.

That's why process is important: you can get lucky and come to the correct results with an improper process (ex: coin flips).

I don't think you can argue that the UK's process was random. There is a process, it went faster, and achieved the same result. Maybe in some other universe it would have missed something and the longer process would have had a different result but that's not the world we live in, in which some not-insignificant number of people didn't die of covid in those 3 months.

I'm not saying the UK's process is random. I'm saying your logic and argument is fundamentally unsound.

Your __logic__ applies just as easily to coin-flips / random-chance to make decisions, and therefore your argument is unable to differentiate between a good system and a bad one.
