NOT.3:4.6 - Keep the operative reading available to its users

Provide the interpretation, the indispensable reading operations and their prerequisites where the intended user can find them. A legend, one worked reading and a reference to a known method may be enough. A new operator needs enough explanation to use it, rather than only a new name.

Stop when the required consequence can be obtained at the declared scope, or when the missing contribution and the next way to obtain it are clear. Retain a slower explanatory route alongside a fluent route when users need to learn, justify or change the operation. A further notation redesign belongs to NOT.7 if the reading works but imposes avoidable difficulty.
