Obviously rumour, but when I did that course at Cranfield it was rumoured that a similar study had been done, showing the selection tests employed by NATS to have absolutely no relation to eventual validation at a NATS unit. The report was supposedly suppressed by a litigious third party company who supplied and administered the test. Sprinkle allegedly through the preceding sentences at your own discretion please.
This was a while ago though, and I know most things have changed since then.
As everyone else says, it's difficult to derive an infallible 'formula' for the psychological profile. Common sense will prevail I'm sure

and the information will just be another piece of data the selection board can consider in their decision making.
