Two forces, no new scores
Silence in a biography is not evidence that perseverance was absent.
This is an unchosen opening or condition in the record, not an estimate of how much luck caused the outcome.
Sequence matters
A different order is a different path—even when some ingredients look familiar.
The useful conclusion
Use this record for information, never for a verdict about your pace or worth.
