Although "an ace of the base" ( as rare of rocking horse sh..t) would probably cope without any simulator time, the ordinary joe most definitely needs an adequate amount to fine tune the SOPs etc. The ATO syllabus will specify the split between sim & ac. Ideally fly the route profile in the simulator, and then try in the ac the following day.
The whole process takes time to absorb. Think about the process of OSMOSIS? The brain can only cope with a certain personal daily rate.
Ideally one event a day initially. Perhaps increasing to 3 events every two days. Five ON, 2 days OFF or equivalent. Two events daily is not recommended. You are simply not getting value for money. After all you are paying for it.
There will be individuals who can cope but they are probably fast jet material ~ a fairly rare breed?
In any event you would not be logging P1 time on the course, apart from the successful test.
