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
- In the thumb section, locate the pitch tiles around the thumb hole.
- Enter the forward or reverse value in the correct tile (forward = toward the center of the ball, reverse = toward the outside).
- Enter the lateral value in the Left or Right tile.
- Review both before saving.

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.
