Signal Velocity: The System Definition

What is Signal Velocity?

Signal Velocity (SV) is a measure of the rate at which conversion signals are generated within a specific, rolling time window. In the growXme system, we prioritize Signal Density over simple Volume—ensuring the algorithm remains in a high-confidence state for scaling[cite: 33, 37].

When Signal Velocity is high, the algorithm gains “momentum.” This state acts as the technical green light for aggressive budget moves, whereas low velocity indicates “algorithmic cooling” and potential performance collapse.

The Mathematics of Momentum

Core Density

Velocity

SV = Signals / Time (hrs)

Measures the density of data feedback loops[cite: 35].

Scale Safe

Scaling Coefficient

Sc = (SV_act / SV_req) × (CPA_tgt / CPA_act)

Determines if budget increases are safe[cite: 39, 40, 41].

Predictive

HVR Score

HVR = ΔSV / ΔCPM

Detects fatigue by monitoring signal decay[cite: 45, 46, 47].

Execution Monitor

Apply these budget actions based on the calculated Scaling Coefficient (Sc):

Sc > 1.5 Aggressive Scaling (30-50%) [cite: 56]

Sc 1.0 – 1.5 Controlled Scaling [cite: 57]

Sc 0.5 – 1.0 Hold Budget / Protect MER [cite: 58]

Sc < 0.5 Reduce Spend / Signal Decay [cite: 59]

Now that we have defined the engine, we must address the primary failure mode of scaling.
