This protocol is designed to perform a before‑and‑after comparative measurement of engine vibration reduction — if any — under three distinct product configurations. It does not assume a result; it measures one.
The purpose is to let users themselves prove — or disprove — the effectiveness of both products in reducing engine vibration, and to observe whether the derivative benefits follow: fuel savings, improved health and comfort, safer and more pleasant driving, and reduced pollution. The protocol is transparent by design: every reading is logged against a baseline, and VPI/VSI are calculated from the user's own data, not from manufacturer claims.
VSI = 0.5·(RMSgnorm) + 0.3·(Velnorm) + 0.2·(PSDnorm) · VPI = 100 × (Mtreated / Mbaseline) · Baseline = 100
