No its not the best method
First line of my post.Now take this and it cancels out the fact you say I am indecisive and
it leaves you with the fact you just can't be reasonable.
It is a self regulating method of finding the most appropriate scientific solution. Its not meant to be the best considering it covers a broad spectrum of science.
Your problem is you seek "the best." This is common among people who in reality, have no idea what people in science actually do. That and religious teaches that perfection may be found in reality when in fact it ain't so.
It is unreasonable to expect something perfect. Don't worry, before i actually started field work as a geotech, i thought every test i would do would bring perfect results if i followed methodology perfectly. The reality is that perfection is unattainable, and if for some reason it is achieved, then something is definately wrong.
For the record i am reasonable to people who can critically analyse. You have not demonstrated such a trait. You simply look for holes. Unless you can theorize something better you're really in no position to criticise.
