Re: SELECT ... WHERE pass_rate_percent > 95;
Yeah, I suspect this is going to end up being a set of rules which are either based on the number of passes or breakdowns since last MOT.
Finding out what those rules are is what the current generation of AIs is quite good for. It might be something like having too many tests done on one day which flags up an investigation but without a lot of testing data from good and bad test centers it would be difficult to identify the conditions.
