Keep versions visible
An overview must identify which complete rules it points to. Chart values are labelled by source and scale, with eligibility conditions left to the full reference. We do not merge several variants into an invented universal standard.
Separate instruction from suggestion
Practice routines are original teaching ideas, not official game rules. Source-based app profiles describe published information. Actual testing claims need a date, device, version or mode, and concrete observations.
