I don't really like advocating a 'standard' recovery whilst doing aeros'. More along the lines of Nose high, speed reducing or nose low, speed increasing and then having a different recovery for each.
The extra height loss would be minimal, especially if you take into account the extra elevator force when you have lots of slipstream at full power. This is a contentious issue and I certainly don't have an impirical data to support any view apart from personal experience.
But if falling out of the top of a loop, then the 'standard' system works O.K, but you have to be careful about speed increasing too quickly and overspeeding the prop if you don't have a CSU.
