DRILL MEASUREMENT FORM

Drilled Dynamics · model validation · one ball per sheet

Date ____________
Measured by ____________
Why this matters: these numbers turn the engine's assumptions into measurements — removed-material density (A3), the undrilled static baseline (replaces A2′/A5), and a real-world check of the predicted drilled statics. Precision targets: weight to 0.01 lb (or ¼ oz), dodo scale to its smallest graduation, sizes/depths straight off the drill sheet.

2 · Undrilled measurements

Undrilled dodo readings are the real baseline the engine currently has to assume. Orient by the CG/pin markers and note how you oriented it.

3 · Layout & holes as actually drilled

Or staple the shop drill sheet to this form — that's better.

Weighing one insert on the gram scale closes ADR-002's density gap for good.

6 · Back at the computer

  1. Open the ball in Drilled Dynamics → Layout & Drill Sheet tab; enter the exact layout, hole sizes/depths/pitches, and the box-sticker top weight, then Compute drilled numbers.
  2. Switch to the Validation tab and type in every number from this form — the app computes measured-vs-predicted deltas, the implied removed-material density, and hints at which assumption any discrepancy points to. Two or three balls across brands is enough to calibrate.

Drilled Dynamics is EXPERIMENTAL; this form exists to test it. Form v1 · serves at http://127.0.0.1:5310/measure.html
