This standard is not for you.

People here are missing the purpose of a standard. No matter the details, it serves as a standard way to brew and conduct tasting for tea traders and professionals. Nit picking whether this or that is fine but unless something drastically changes (such as dynamic range of tastes), it won’t matter much. Whether it follows tradition in your specific region is also irrelevant. This isn’t the “right” way to brew either nor does it try to.

Ironically, the bickering here is exactly why a standard is needed. It is proving its point.
