Company checklists are basically copies of the Flight Manual because when the company takes delivery of a new type that is all they have to work on. The manufacturer writes them to cover itself and also provide guidance to customers to which English (or French) is not their first language. An organisation that has only one executive version does not write checklists, they use the manual. The 332L my company bought from Samsung was an example,
It follows that it is overdone and repetitive. Not only that the people that write the company checklists draw on their experience on other types which is why 332s are flying instrument patterns at the same speed as S61s.
When we flew the S76A single pilot we had a flip out board by the side of the instrument panel that told what to check Not what to do but just to check it.
