## Overview

This is the whole 2026 study compressed to a handful of charts: one
summarizing every standard-speed vane build, one summarizing every
standard-speed broadhead build, and the two headline findings from the
front-of-center work. If you only read one page here, make it this one.

## Vane Overview

Each dot is one of the {stdVanes.length} standard-speed vane builds in the
test. Drag on Y, restorative lift on X, deer-weighted Lmax as color.
Bottom-left is low drag and more restorative lift; yellow is quieter to a
deer.

Said simply, the bottom-left yellow dots are the best performers.

actual group photos.

## Broadhead Overview

Each dot is one of the standard-speed broadhead builds, plus a Gold Tip
100gr field point on the same arrow as a baseline reference. Drag on Y,
mean radius on X, deer-weighted Lmax as color. Bottom-left is low drag and
tight groups; yellow is quieter to a deer.

## Front-of-Center: Does More FoC Help?

What does extra weight up front actually do, on its own? We compared arrows
of the same total weight but different FoC. Bumping FoC up by 5 points
(say, from 12% to 17%) tightened broadhead groups at 70 yards by about 2
inches on a well-tuned bow, and about 1 inch on a torqued bow.

[Figure: PlotSections]

Predicted change at +5 percentage points of front-of-center, in inches at
70 yards, with total arrow weight and the other build details held equal.
Bars are 95% confidence intervals; lower (left of zero) is better. Solid
dots are results we're confident about; hollow dots are ones where the bar
still crosses zero (the data can't tell).

## Front-of-Center: Stiffer Shaft vs. Lighter Point

There are two ways to give an arrow stiffer dynamic spine: a stiffer shaft,
or a lighter point. We tested each one separately, with FoC already
accounted for. Each move tightened broadhead groups on the tuned bow by
about three-quarters of an inch.

[Figure: PlotSections]

Predicted change for two stiffer-dynamic-spine moves: a static-spine step of
+{NOMINAL_SPINE_STEP_UNITS} nominal spine units stiffer (e.g. a 300 shaft to
a 200) and a {POINT_WEIGHT_STEP_GR}-grain drop in total point weight.
Front-of-center is already in the regression, so each row isolates the
component on its own. Bars are 95% confidence intervals; lower (left of
zero) is better. Solid dots are results we're confident about; hollow dots
are ones where the bar still crosses zero (the data can't tell).
