I think you are at crossed purposes. In EU land it is necessary to complete Base training after the LST to receive the type on licence. Most airlines, to save cost and build confidence, do an hour os so in the sim prior to live a/c circuits. My comment is that once this is done some airlines then discourage/forbid this profile to used on line with pax aboard.
When asked why not, one reply given was that,
"Base training circuit was a requirement for TQ and very specific. On the line it would be rare to fly a level timed circuit, but rather a self-judged descending CDA circuit, which was not trained and therefore liable to screw ups and costly GA's. Visual circuits will only be flown into an OM final which negated the benefit of a shortened visual circuit anyway. The benefit gained from the training required was not worth it."
OMG. So doing it the way we had always done it, by demonstration & practice on the line, was now deemed insufficient & inappropriate and unnecessary. The problem is evolutionary because with rapid commands there is no-one to demonstrate and coach. I retired a couple of years, after doing what I had done for 35 years, was banned. 2 years previously, & the last time I had the opportunity to arrive overhead at 4000' and fly a raw data Mk. 1 eyeball CDA to 2nm finals, the F/O had the gumption to ask "how did you do that?" & "why are we not doing it more and being taught how to do it?" Good lad, and then it was banned.
