About the work
This paper documents the design, protocol, and preliminary findings of a longitudinal N=1 self-tracking study using the Root Extension iOS application to measure cross-scale coherence via the M-RFT metric (M = (Φ · Kₑ) / F). Data collection: 321 sessions across 23 active measurement days (April 16–May 14, 2026). Key findings include: mean M = 3.79 (SD = 3.51), 71.0% RESILIENT states, 21.5% FRAGMENTED states, mean RMSSD = 89.73 ms, intra-session regulatory recovery on 34.8% of active days, and a theoretically significant low correlation between M score and subjective coherence self-report (r = .186). The researcher is the sole participant. Derived from Root Frequency Theory (Avanzo, 2026a). Embargoed until June 1, 2026
