Sources & methods
Percentage of all positive selectedStakeValue in a Classic round held by its ten largest accounts, after summing each account’s submitting models. The top ten are ranked separately each round. Public ownership observed at collection time reconstructs historical accounts. Exact shares require every staked model’s owner. When ownership is incomplete, lower bounds give each unknown model a separate account and upper bounds assign all unknown stake to the largest known account. Missing unstaked models do not affect this measure when positive-stake counts reconcile. Unreconciled stake counts and zero stake remain null.
Models are grouped by account before ranking each round. Bounds describe possible ownership assignments, not statistical confidence intervals.
Public ownership collected later may differ from ownership during the round. Ownership mappings can be cached for up to 30 days. Null exact shares must not replace the bounds or become zero.

JSON fields
Paths use [] for array items and * for metric keys such as corr20 and corr60. Absent fields or null values mean unavailable information; a numeric zero remains a real observation.
