Good points especially regarding overload and spare capacity which varies from one person to another.
The point of overload is often the crash point.
I can remember an instructor who flew a PA28 long distance in awful conditions IMC.
When he landed he claimed that if someone had asked his name he would have looked at them in a blanked daze.
We all have different brains! some are more visual with an ability to take in loads of visual information quickly others are recollective.
I always think of different computers! They all have memory and Graphic cards but some are designed for gaming with the need to process "visuals" fast.
As with the computer overload the Graphics card and the screen freezes.
Pilots with fast Graphics cards and loads of onboard memory naturally can handle as it happens information better and are usually better at picking up their game to suit the situation.
Those with slower Graphics cards can still do a good job in most circumstances but rely more on training and storing information in the main memory banks.
Anyway thats how I see it.
