Read it piece by piece
Symbol S
S is part of the quantity the equation computes from the expression on the right.
Symbol g
g occurs below the fraction bar. The quantity above the bar is divided by this expression; zero is excluded as a denominator.
Symbol p
the share of a change’s total cycle time that code generation itself used to consume before Claude Code, so (1-p) is the share consumed by review and everything else.
=
The expressions on both sides represent the same quantity under the stated assumptions.

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.
Denominator: (1-p) + p/g
The complete quantity below the fraction bar; it must be nonzero for this division.
Denominator: 1-p
The complete quantity below the fraction bar; it must be nonzero for this division.
How to interpret it
With a fixed numerator, increasing a nonzero denominator reduces the fraction. Read it with the definitions, units, and assumptions supplied by the article.
What the article says around this equation
That framing is worth making precise, because it is a structural claim, not a figure of speech. Let p be the share of a change’s total cycle time that code generation itself used to consume before Claude Code, so (1-p) is the share consumed by review and everything else. If generation alone speeds up by a factor g , total cycle time scales as (1-p) + p/g , and the achievable speed-up in total cycle time is . Amdahl’s law was originally about parallel processors, not engineering teams, but the constraint has the same shape: a serial bottleneck that does not scale caps the benefit of accelerating everything around it, no matter how large g gets. For a team, review is that…

That framing is worth making precise, because it is a structural claim, not a figure of speech.

If generation alone speeds up by a factor g , total cycle time scales as (1-p) + p/g , and the achievable speed-up in total cycle time is . Amdahl’s law was originally about parallel processors, not engineering teams, but the constraint has the same shape: a serial bottleneck that does not scale caps the benefit of accelerating everything around it, no matter how large g gets. For a team, review is that bottleneck.
