4.5.3 Entering vertical and lateral pitch for thumb

4.5.3   measurement

Thumb pitch works exactly like finger pitch — you enter it into the pitch tiles around the thumb hole, and the tile is the direction. There's no direction to select from a dropdown. For the full mechanics of the pitch tiles, see 4.4.3; for the terminology, see 4.1.4.

🛠️ How the Thumb Pitch Tiles Work

  • ✅ Forward — points toward the center of the ball. Enter forward pitch in the forward tile.
  • ✅ Reverse — points toward the outside of the ball. Enter reverse pitch in the reverse tile.
  • ✅ Lateral — the Left and Right tiles, by position.

Forward/reverse and lateral are separate tiles, so the thumb can carry both at once. The thumb and fingers are fitted independently — it's normal to have reverse on the thumb and something different on the fingers.

Note: To apply a pitch against a tile's default direction (for example, Right pitch on the left-side tile), scroll to the absolute bottom of that tile's drop-down for the cross-direction values listed as Rx, where x is the desired pitch.

⚙️ Thumb Pitch Is Manual

Thumb pitch is manual data entry — there's no automation and no error validation behind these fields. Spectre records exactly what you type.

📋 Entering Thumb Pitch

  1. In the thumb section, locate the pitch tiles around the thumb hole.
  2. Enter the forward or reverse value in the correct tile (forward = toward the center of the ball, reverse = toward the outside).
  3. Enter the lateral value in the Left or Right tile.
  4. Review both before saving.
  • 4.4.5 — Inputting finger pitch (the pitch-tile mechanics)
  • 4.1.4 — Pitch terminology: Forward, Reverse, Lateral, Zero
  • 4.5.4 — Thumb insert type and size

Tip: Because forward points to the center of the ball and reverse to the outside, the sheet layout tells you the direction — no sign convention to memorize. Enter each value in the tile that matches the direction you measured, and read it back since nothing here is validated.
