Views-to-subscriber conversion
Sub gain relative to weekly view volume
Ratio: new subs per 100M views. Weeks with ratio = 0 may indicate a data anomaly.
Subscriber surge accelerating
+100.0K subs gained on Mar 11 — the highest single-week gain in this 8-point window. Likely driven by a high-performing video upload.
Mar 10 sub anomaly
Zero subscriber growth despite 15.1M views that week. Possible data artifact, or audience retention without conversion — worth monitoring.
Views floor is very high
Even in "off" weeks, Mark Rober sustains 7–12M weekly views. This baseline is a strong moat — hard for competitors to match at scale.
