The two readings
The account balance answers one question and conceals a better one.
Growth is a scalar: the account is larger or smaller than it was. Capital quality is a description of how that change was produced, assembled from drawdown depth and band, the volatility ratio, dollar-per-R, drawdown frequency, and the efficiency and health measures that compress them. The two are only loosely coupled, and the loose coupling is the entire reason this tab exists as a separate layer rather than a column on the dashboard. Two weeks with identical returns can differ completely underneath: one delivered smoothly with contained drawdown and stable dispersion, the other delivered through a deep trough and a violent recovery that happened to finish above where it started. The balance records them as equivalent. Everything about their sustainability differs, and the difference will show up in the balance eventually — just not this week, and by then the pattern will be several months old.
Growth appears in the first two columns and the responses are opposites. Reading the balance without the quality block cannot distinguish them, which is why a profitable stretch is not by itself evidence that anything is working.
