What this part means

The lower label selects a particular version, component, or indexed member of the quantity. For example, x₀ and xₜ can be values at different positions.

Its job in the formula

A subscript distinguishes a version, component, step, or member of a quantity. It does not automatically mean multiplication.

The passage around this formula

and the marginal value of instrumentation is whatever it removes from τm\tau_m . Written this way the ranking changes sharply from intuition, because τm\tau_m varies over several orders of magnitude across the list while λm\lambda_m and ℓm\ell_m vary by much less. Detection latency, not frequency or severity, is what dominates.
