In the past, I’ve mentioned keeping records of my shooting. I keep scores, where I trained or competed, the bow, arrows, tips and other bits of data. The other data often includes physiological and nutritional data. The physiological and nutritional data remains a bit too sparse to draw conclusions. The equipment data is more enlightening.
One of the most frequent paper targets I shoot is a 5-spot. The data on this target spans twelve months, January 2014 until January 2015. The earlier data scores are lower than the scores recorded later in the year. There is a clear progression of improving scores. However, the improvement is not statically significant.
Statistical significant is important when determining whether or not a test method difference is meaningful. In sports, data that isn’t statistically significant doesn’t mean that something important has or has not occurred.
A great example are data that were collected during my cycling career. For months I repeated a 10-mile time trial to measure the effect of a training technique. The data wasn’t statistically significant. The improvement in time to complete the trial was a major improvement – about 2 minutes. Two minutes could be the difference between 1st place and 10th place.
In archery, the data collected revealed that over the course of the year I had a 6% improvement in my scores, which leveled out after a few months. What is interesting is that over the second half of the year, my average is a 1% below a consistent 300 (100%), or an average score of 298. Is it me, or is it the equipment?
Scoring a 300 every time I practice on a 5-spot isn’t likely. Still, improving my 5-spot average is possible. So, where do I make minor improvements that can defeat one or two poorly placed shots?
There are little adjustments that must be made in the physiological (form) of my shooting. These seem somewhat apparent when I lose form. In the meantime is there anything else missing?
In all sports, there is the equipment. In cycling there was a time I competed on a mid-level racing bike. Not the best bike and certainly not the worst. Then, I was given a bike that had been ridden by one of the professional cyclists in the Tour de France. Not a replica, the very same bike ridden by Rodolfo Massi before he was disqualified for using performance-enhancing drugs. When I rode the bike, it was nearly 3 pounds lighter than my previous one; it felt like I was cheating. I wasn’t taking performance-enhancing drugs, but in this case, the change in my equipment was significant, especially during climbs.
In archery very minor adjustments have an impact. My bow is a Mathews Apex 7, a bow with a good track record in tournaments. My sight is a top end Axcel with a high end SA Scope. My release is a Scott Pro Advantage. My arrow rest is a mid-range model that has raised eyebrows and earned questions.
Thus far I have been fairly pleased with the arrow rest barring a time or two when it didn’t drop and once when it broke. But, a bow technician asked way did I have such nice equipment and still used a mid-range rest. Does my rest account for a very slight variance in accuracy?
If it does, that occurrence might only happen less than 1% of the time. Maybe it is that 1% of time when a very slight “arrow rest” variance led to a less than perfect shot. If so, maybe it accounts for the 1% gap recorded from my average to perfection. (I do occasionally shot a 300)
In practice today, I used my mid-range arrow rest. I shot a 5-spot for training this morning. Later, today I’ll work on yardage. Later this week, I’ll investigate changing my arrow rest to a top end model. Today, I shot a 298. The lessor shots where entirely not the fault of the arrow rest.
