How much does draw weight really matter for your score?

Part of the complete guide: How to improve your score in archery

Sooner or later the question comes to everyone, usually while looking at the equipment of someone better: "if I went up in poundage, would I score more?". It is a fair question, and it deserves a better answer than the two extremes circulating on the range: the "more pounds, more points" of whoever wants to sell you new limbs, and the "poundage means nothing" of whoever stopped asking. The truth sits in the middle, and for once the middle can be calculated.

One note on terms, for whoever lands here first: draw weight is the force needed to bring the bow to full draw, measured in pounds, and the nominal value printed on the limbs refers, by industry convention, to a 28 inch draw. What it means to pick the right number for you is covered in the guide to choosing draw weight. Here the question is drier: how much of it turns into score?

What the pounds actually buy

Let us start with what the pounds genuinely deliver, because they do deliver something. More draw weight means more energy passed to the arrow, and therefore more speed out of the bow. And a faster arrow has three concrete advantages, all real, all measurable.

The first is a flatter trajectory: over the same distance the arrow drops less in flight, so there is less drop to compensate for in your aim. The second is a shorter flight time: the arrow spends less time in the air, and everything that works on it during the flight, wind above all, has less time to work. The third is tolerance to range errors: if the distance is judged wrong, a flat trajectory forgives a few meters of error far better than an arched one, because the arrow's height changes less from one meter of its flight to the next.

Put like that, the case sounds closed: more pounds, more points. But there are two calculations this version skips, and they are the two that decide the game.

The honest physics: the square root

The first calculation is that speed does not grow in proportion to the pounds. To a first approximation, for the same draw length and bow efficiency, the stored energy grows roughly in proportion to draw weight. But arrow speed grows as the square root of that energy, for the same arrow mass: that is elementary physics of motion, not an opinion. The practical consequence is that poundage increases deliver less than they promise.

An example that is nothing but arithmetic: going from 30 to 36 pounds is a 20% increase in the effort you sustain on every single arrow, for the whole competition. Speed, though, grows by about 10%, and flight time shortens by roughly the same fraction. You paid twenty to take home ten. And the price is paid by your body on every shot, while the gain only shows where trajectory truly matters.

The calculation nobody makes: control

The second calculation is the decisive one, and it is not about the arrow but about you. The extra pounds are sustained on every shot: through the aim, through the hold, through the final seconds, for dozens of arrows and for hours. A draw weight beyond your current capacity shows up on the target with a precise signature: bow arm tremor that grows, a draw length that quietly shortens, an anchor that turns hurried because holding is expensive, a second half of the competition that scores worse than the first. And, over the long run, a load the body is not ready to absorb is among the factors that favor overuse injuries.

Here the choosing guide says it in a sentence worth repeating to the letter: an archer who handles 32 pounds well shoots better than one pulling 40 without sustaining it. The number, on its own, means nothing. What counts is how much of that number you govern, from the first arrow to the last.

The angle comes back to collect

There is a clean way to put the two calculations together, and it is to return to the geometry of the target. Control errors are angular errors: they are born at launch, in the shot, and they grow in a straight line with distance. One tenth of a degree, as I showed when writing about groups and distance, is worth about 12 centimeters at 70 meters: an enormity, on a 10-ring that measures 12.2.

Now put them on the same scale. The extra speed works on the vertical plane and on the wind: it helps, but indirectly and partially. The extra tremor works on every axis, on every arrow, in proportion to the distance. If the pounds you gained cost you even a fraction of a degree of steadiness, the points ledger almost always closes in the red: what the flat trajectory gives back on the vertical, the trembling hand burns twice over across the whole target. It is why, at known distances and in light wind, the more precise archer regularly beats the more powerful one.

Where the pounds really pay

Having named the cost, honesty requires naming where the scale tips the other way, because there are contexts in which the flat trajectory is worth a lot.

Notice what the first two contexts share: in disciplines where the distance is known and the target stands still, the value of speed shrinks considerably, because drop gets compensated once and for all with the sight setting. Where the distance is uncertain or the air is working, trajectory enters the score on every arrow. Whoever shoots 3D and field has real reasons to care about speed; whoever shoots indoors at 18 meters, almost none.

So how do you decide?

The honest sequence is this. First: draw weight is chosen on control, with the criteria of the dedicated guide, and the operational test is holding up to the end of the competition, not the strength feat of a single shot. Second: you move up only once the current step is fully governed, in small increments, giving the body its weeks of adaptation at every change, as with any increase in load. Third: at every change of poundage you re-check the tuning, because dynamic spine shifts even with small adjustments, and a more powerful bow with untuned arrows returns fewer points than a lighter, tuned one.

And there is a simple test to know which side you are on: compare the first and the last series of your long sessions. If the last group opens clearly compared with the first, your problem today is not the speed you lack: it is the load you already fail to sustain. Going up in pounds, from there, would mean paying more for something that is already costing too much.

The questions I get asked most

Does more draw weight mean more points?
Not in itself. Pounds buy speed, and speed helps where trajectory matters: unknown distances, wind, long range. But the return grows only as the square root of the energy, while lost control is an angular error that distance multiplies. At known distances the more precise archer almost always beats the more powerful one.

How much speed do I gain by going up in poundage?
Less than it seems: to a first approximation, for the same arrow and efficiency, +20% in draw weight is worth about +10% in speed, because speed grows as the square root of the energy. Every extra pound returns a little less than the one before.

When does it make sense to increase draw weight?
When the current step is governed to the last arrow of a competition, with no growing tremor and no group opening late in the session. Move up in small steps, give the body a few weeks of adaptation at every change, and re-check your tuning, because dynamic spine shifts with the pounds.

Does high draw weight cause injuries?
It is not the number itself: it is load the body is not ready to absorb. A draw weight beyond your current capacity, combined with volume, is among the factors that favor overuse problems, with the shoulder first in line. Gradual progression is the best protection, and it is worth more than any accessory.
