FAQ

Why is handicap truncated?

Most leagues drop the decimal rather than rounding, which is what this calculator does.

What if my average exceeds the basis?

Your handicap is zero — you bowl scratch.

Accuracy and limitations

  • Estimates assume standard, average conditions — local rules, pricing, and materials vary.
  • Results are rounded for readability; add a buffer before ordering, booking, or committing.
  • Double-check anything with a real cost attached against a local quote.
