Definitions

In plain terms

For a newest-heavy length-n WMA, oldest-to-newest weights are commonly 1 through n.

Technical

The contract fixes orientation, start weight, increment, window length, normalization, and rounding.

Scope

Linear weighting is one WMA convention, not the definition of every weighted average.
