This document proposes a new Mass-Charge modeling approach to analyze statistical fluctuations in amino acid charges in SARS-CoV-2 variants like Omicron. It introduces a normalized derivation using Excel and Matlab algorithms to examine charge and mass relationships in coronavirus spike proteins. The approach provides insights into the evolving bioinformatic trends affecting infectivity and virulence. Key contributions include a new running semi-covariance notation to analyze non-linear patterns, and integrating genomic data to set up an ending time prediction framework for the pandemic by continent. Results compare SARS-CoV-2 spike protein sequences to other coronaviruses using simplified complex variances. Findings suggest mutations depend on region and that flu virus is closer genetically to rat virus than
