2.6.4 Auto-Populate Lateral Pitches

2.6.4   auto

The Auto-Populate Lateral Pitches is another time saving auto-suggestion for Spectre Cloud.  Pre-requisites for this to work will be Bowler Hand and Grip Type, both of which are System Defaults that you can setup in your settings.

📐 What values are populated

Lateral pitches will be auto-populated based on the header of the spec sheet.

  • ✅ Bowler Hand: RH or LH will dictate the proper direction of the lateral pitches in the fingers.
  • ✅ Grip Type: will determine which values are used.
  • ✅ Will flip values or change values if one of those two values are changed during the data-entry process.

Defaults


 Right Handed
Left Handed
Finger Middle Ring Middle Ring
Conventional 1/4 L 5/8 R 1/4 R 5/8 L
Finger Tip 3/8 L 1/2 R 3/8 R 1/2 L

🛠️ Enabling or Disabling Auto-Invert

  1. Navigate to Settings from the top menu.
  2. Find the Populate lateral pitches option.
  3. Toggle the setting on or off. 
  4. The change takes effect immediately when you will create a new drill sheet.

📊 Auto-Invert in Common Workflows

Auto-Invert is most relevant in three specific situations. In each case, enabling the setting means the fitter can proceed without manually checking and reversing lateral pitch values.

Workflow Without Auto-Invert With Auto-Invert
Cloning a RH spec sheet for a LH bowler Lateral pitch values carry over unchanged — must be manually reversed before drilling Lateral pitch values are automatically mirrored on clone
Switching a bowler's handedness setting on their profile Existing lateral pitch values remain as entered — no automatic correction Lateral pitch values on associated spec sheets are updated to reflect the new handedness
Creating a new LH spec sheet using a RH template Template lateral pitch values must be manually inverted before use Template lateral pitch values are automatically mirrored when applied to a LH bowler

Note: ⚠️ Verify with your Spectre team: confirm which of the three workflows above Auto-Invert actually applies to in the current version of Spectre Cloud, and whether "switching a bowler's handedness on their profile" retroactively updates existing spec sheets or only affects new ones created afterward.

  • 2.6.3 — Auto-CLT: lateral pitch of fingers based on CLT chart
  • 2.6.2 — Pitch suggestion: auto forward pitch based on hand flexibility
  • 2.6.1 — Overview: why leaving all auto-suggestions on saves time
  • 2.6.5 — Next auto-suggestion setting (if applicable)
  • 2.4.1 — Does your machine display right pitch as positive? Y/N
  • 3.x — Bowlers: recording handedness in a bowler profile
  • 4.x — Spec Sheet: cloning and applying templates

Tip: Left-handed bowlers make up roughly 10–15% of the bowling population — a busy shop will fit several per week. Auto-Invert is a small setting with a disproportionately large safety payoff: one enabled toggle prevents a whole category of handedness-related drilling errors from ever reaching the press.
