|---|---|---|
| October 1, 2026 | 101.2 | The decline corrects August's LinkedIn input. LinkedIn's own data shows no jump; the suspected cause is a wave of spam accounts that was later scrubbed from the record. The other ten platforms were essentially flat. |
| September 1, 2026 | 104.2 | The largest monthly move recorded, and effectively all of it is LinkedIn. |

- Calculation Method
- Weighted mean of follower counts across 11 platforms, indexed to October 2025 = 100. Weights: KmikeyM accounts 0.35, Substack 0.30, LinkedIn 0.09, X 0.09, Instagram 0.07, YouTube 0.04, Bluesky 0.02, Mastodon 0.01, KmikeyM LinkedIn (business) 0.01, Facebook (personal) 0.01, KmikeyM Facebook (business) 0.01. Weights sum to 1, so the composite is denominated in followers. Index = composite / 3041.9 × 100, where 3041.9 is the frozen October 2025 composite. See lib/sci.ts.
