I fly in a MC invironment. We spend a long time checking the aircraft and all the other things required before the flight so that the aircraft is ready to go when the PAX arrive.
If for whatever reason we are really tight on time (PAX arrive late with Slot times) We may even on occasion have the one engine started)
Normally we run through the checks in the correct MC manner.
On occasion because I know my co pilot well and the aircraft very well I will run the checks from memory while getting the co to read them out and visually check the items on the move. We still confirm those items.
The point I am tying to make is that as a pilot there are occasions when you have to up the game and knowing not just the aircraft but the check items facilitates a smooth, prompt operation.
There are pilots who plod through the checklist as if they are reading a recipe book (add three teaspoons of sugar, stir three times etc)
One slow speed which can give the PAX the idea that you are such a bad pilot you need a guide to fly a bit like the German pilot in those magnificent men and their flying machines with a how to fly an aeroplane hand book. He was fine until the handbook blew out of his hands and stuck on the tail of the plane

where was he then??? He had to climb out and retrieve it)
I still hold with the fact that there are occasions on the ground and in the air where knowing your checklist from memory with the checklist as backup is a far safer way than letting the aircraft run away from you and other events overtake you.
The times when you should be on page 4 of your checklist not page 2
