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
More fundamentally, even a perfectly executed, continuously updated tracker cannot make the comparison one-dimensional, because quality at a given cost and latency is a function of a whole vector of settings — reasoning effort, context length used, modality, batching — and two systems compared at one point in that vector can reverse their relative standing at another point: . A model that leads at high cost and maximum reasoning effort is not guaranteed to lead at the low-cost, low-latency point a production deployment actually needs, and a comparison that quotes only one of those two points without saying which is not wrong so much as silently incomplete.
