What does "cross-practice CV" mean? (plain English)
CV = Coefficient of Variation. It measures how spread out our practices are from each other — not how high or low the average is. In one sentence: "How much do our practices differ from one another?"
You take every practice's growth rate, find the average, then measure how far the typical practice sits away from that average. Divide the spread by the average and you get CV. Because it's a ratio, you can compare it across very different metrics (dollars, percentages, patient counts).
Analogy: Two classes both average 75% on a test. Class A: everyone scored 73–77 (low CV — consistent). Class B: half scored 50, half scored 95 (high CV — all over the place). Same average, completely different story. SGA's CV of YoY growth = 3.8, which is very high — the network average looks healthy only because a handful of booming practices cover for many shrinking ones. Planet DDS's whole 2026 thesis is that low spread = operational maturity. A high CV is the thing to fix.
