A Preliminary Descriptive Reference Scale for Balance Gap: BG-10 Exploratory Coding Layer v0.4

Key Points

This note aims to introduce a new framework for understanding balance gaps in body proportions and tracking them over time.
Descriptive exploration of the BG-10 scale for observing balance gap levels.
Classification of balance gap into 1-10 coding levels based on proportional discrepancies.
Discussion on the applicability of existing methods like BMI and BIA in relation to balance gap.
BG-10 coding levels range from 1 to 10, with lower levels indicating less discrepancy in body proportions and higher levels indicating greater divergence.
BG-10 is not intended as a diagnostic tool or a replacement for existing evaluation methods, but rather a framework for discussion.

Abstract

This public concept note explores BG-10 as a preliminary descriptive reference scale for discussing Balance Gap (BG) within visible-body proportion observation. Existing systems such as Body Mass Index (BMI) and Bioelectrical Impedance Analysis (BIA) remain valuable for evaluating body mass and internal composition variables. However, these systems were not originally designed to describe upper-lower proportional discrepancy, silhouette transition relationships, structural balance, or longitudinal visible-body organization. Within the broader exploratory framework of visible-body proportion interpretation, Balance Gap (BG) conceptually describes the absolute discrepancy between upper-body spread and lower-body spread relative to the waist transition. This note introduces BG-10 as a simplified descriptive coding layer that translates raw BG values into 1–10 observational coding levels for methodological discussion and longitudinal tracking purposes. Lower coding levels indicate smaller proportional discrepancy, while higher coding levels indicate broader relational divergence requiring wider contextual review. The BG-10 structure presented here is exploratory only. It is not a diagnostic tool, medical assessment system, beauty ranking system, or replacement for established physiological or anthropometric evaluation methods. Specific calibration systems, computational weighting structures, adaptive interpretation rules, implementation protocols, and protected interpretation-engine details are intentionally not disclosed in this note. This archive is intended solely for exploratory scholarly discussion, conceptual refinement, methodological comparison, and future interdisciplinary development. Version:v0.4 — Public Concept Note Open for community feedback and interdisciplinary refinement.
