We might need to define "Shortcut" as either a better method based on validation and experience of a technique or a shortcut based on an assumption.without validation.
The shortcut "leave to the expert" can be a two edged sword. My personal experience of experts on the issue of reduction methods for gas kilns leaves a wide path for many different methods and opinions , some good, some not so good.
Education comes at a cost, whether academic and/or sweat equity. It sometimes takes a long time and a lot of clay to find the shortcut.
