Why HailTruth Is Different

We're the only platform that uses real atmospheric physics to calculate hail damage

CAPE-Based Density

Calculate actual hail density using atmospheric sounding data and CAPE values. Dry, mixed, and wet formation regimes with real physics.

Terminal Velocity

Reynolds number calculations with drag coefficients. Real air density from weather data. Accurate impact velocity predictions.

SPEAR Index v2.0

Wind-driven trajectory analysis with cos²θ energy transfer. 13 industry-standard materials with field-validated damage thresholds and Federal Rule 702 compliance.

The Science

SPEAR Index™ vs. Industry Standard

Same scientific rigor as Haag Engineering—the 40-year industry standard—with better real-world accuracy. Every calculation verifiable.

Key Point for Attorneys

SPEAR isn't "alternative science"—it's the same physics Haag uses, with additional corrections for real-world conditions. The terminal velocity equation, drag coefficients, and kinetic energy calculations are identical. SPEAR simply inputs more accurate values for ice density and air density.

The Elevation Problem

Why Altitude Matters

Air density decreases with elevation, increasing terminal velocity and impact energy. This is physics, not opinion.

LocationElevationAir DensityEnergy vs. Sea Level
Houston, TX(Haag baseline)~50 ft1.225 kg/m³
Denver, CO5,280 ft1.047 kg/m³+17%
Santa Fe, NM(documented case)7,200 ft0.946 kg/m³+29%

Real-World Impact

At Santa Fe's elevation, a 1.0" hailstone delivers energy equivalent to ~1.15–1.20" at sea level. An engineer applying Haag's 1.25" threshold without altitude correction is using the wrong benchmark.

The Ice Density Problem

Not All Hail is Created Equal

Haag assumes pure ice (0.916 g/cm³). Real hailstones vary significantly based on storm intensity.

vs. Haag assumption

What This Means

In severe storms (the ones that cause major claims), Haag's fixed density assumption typically overestimates hailstone mass. SPEAR uses actual atmospheric conditions to calculate what the hail really weighed.

Why This Matters

The deeper the Hail Growth Zone and higher the CAPE, the longer hailstones stay aloft accumulating mass. This is why size alone doesn't tell the whole story — a 1.5" stone from a high-CAPE storm hits harder than a 2" stone from weak convection.

No other platform analyzes the actual atmospheric conditions that created the hail.
