How the Saint Bernard Calculator Works

1

High-Sensitivity Dynamic Modeling

We use a proprietary High-Sensitivity Dynamic Model calibrated specifically for Saint Bernard development. This accounts for the biological reality that growth velocity decelerates sharply as a puppy matures, ensuring pinpoint accuracy for both 8-week-old puppies and older teenagers.

2

Maturity Window Calibration

A Saint Bernard typically reaches its full skeletal structure around 24 months. Our algorithm applies a specific maturity multiplier that adjusts the projection as your puppy approaches this target window.

3

Standard Deviation Check

Every projection is cross-referenced against the Saint Bernard breed standard (120–180 lbs). While estimates can begin at 6 weeks, data collected after the 12-week mark provides the highest statistical confidence.
