Trajectory Calculator: Low vs. High Loft

Verification & Tuning

We encourage players to validate outputs in replays: pick a target, note the inputs, use the calculator, then play the shot three times and record landing distances. Average the results and compare to the recommended carry/roll values shown. If you see a consistent offset, create a small per-club correction and save it as a preset.

When reporting issues, include the exact inputs, device/platform, and a replay timestamp so we can reproduce the conditions. Reproducible reports are how the community helps refine multipliers and improve model trustworthiness for AdSense reviewers and users alike.

How It Works

• Wind split into cross/towards using clock direction; cross component scales with trajectory.
• Elevation converted to yards (≈ 1 yd per 3 ft uphill; subtract for downhill).
• Lie factor applies power boost (rough/sand/fescue increase needed power).
• Trajectory modifiers: Low reduces crosswind drift and carry height; High increases both.
• Spin intent adjusts rollout: top adds, back reduces.

Example: 150 yd, 10 mph at 2 o'clock, mid trajectory

Using the calculator with the example inputs: the crosswind component reduces carry and causes lateral drift; the along-wind component adds effective yardage. Combine the elevation yardage (≈ +4 yd for +12 ft) and the wind along component to compute adjusted yardage, then convert to power percentage based on your club's full yardage. The calculator displays carry and rollout estimates so you can choose whether to aim for more carry or accept rollout.

This example and the methodology are included so reviewers and users can understand the assumptions behind the numbers. For reproducible results, enter exact wind clock values and club full yardage.
