In my view 40 hours is already a bit low, and giving people credits off that would turn out a pretty low quality pilot.
Apart from the exceptions who are good at everything, most people take 50-60 hours in my experience before they can be considered any good and suitable for test.
Personally I think the LAPL(H) is not needed and hope people will do the EASA PPL(H) it's only 5 hours more and the Qual X-C is 100nm with 2 full stop landings rather than 80nm with 1 full stop landing
