That's not exactly as i see it.
I interpret it as being that you will put the same amount of hours in your log book as we always have, it is just that only 3/4 or 2/3 of the augmented hours will go towards your 100 hours per 28 days limitation.
So, it is possible that you could log 150 hours in your log book, but only have flown 100 hours as far as the GCAA is concerned in regard to the 100 hours in 28.
