There are loads of "methods" out there that go against the spirit of what they are trying to achieve. Which is of course ensure you have some experience in these matters and actually know what your doing.
These days I don't think they know what they are trying to achieve which is the crux of the problem. They never really realised what was happening with the JAR rules apart from bun fights on here.
The level of supervision is so variable. You have some that put some effort in and sit in on briefings and de briefings. And others who are only there to keep things legal (that's if they are there at all)
Personally I was restricted for a whole 5 weeks during summer wx. Level of supervision was nil apart from 2 solo 's sent to the FI unrestricted.
Its perfectly possible for the FI to get unrestricted with never having taught someone from zero to first solo.
