Understanding distance variance

Sometimes it can be a blow to the ego to go to a new course where the ball seems to go nowhere and you just can’t bring yourself to hit 5-iron, for example, when you could normally hit 7-iron.

But if you want to score well, it’s something that can be important to understand and accept…that is, that distances can vary quite dramatically from course to course.

To illustrate this, let’s take a look at the average driving distances for the field in the following PGA Tour and European Tour events from 2012.

As you can see, despite more or less the same players playing each week, there’s a 74.1-yard variance between the tournaments with the shortest and longest average driving distance for the field.  That’s a huge difference!

It’s feasible that there were extenuating circumstances taking place during the events on the extreme ends causing such a broad gap.  There may have been severe weather, for example, or perhaps a certain course required the use of more woods, hybrids, or irons off the tee. But in general, to account for things like this, the driving distance averages for Tour events are generally taken on two holes where the wind blows in opposite directions and also where the players are likely to use driver.

Even still, let’s take out a few of the extremes on the short and long ends. When we do this, note that the bulk of the average driving distances range between 280 and 300 yards.  That’s still a 20-yard difference from event to event and course to course.  It’s not as much as 74.1-yards but it’s still worth noting.

I remember this was also the case when I used to compete in long drive. My longest drive in competition was a 421-yard drive in Warner Springs, Calif., to win a qualifier for the RE/MAX World Long Drive Championships. Granted, it set the grid record but it was still on firm ground at an elevation of about 3,130 feet.  Conversely, the 381-yard ball I hit to win the Pinnacle Distance Challenge was actually a much better drive, despite being 40 yards shorter. However, the ground was a little softer and the elevation was much less — around 466 feet.

In general, Tour players and their caddies understand and are good at accepting that distances change based on conditions.  In fact, determining these distance variances are actually one thing that many of them are doing during practice rounds…and it’s also partially why they can subsequently go tear up the course in the tournament with a few as one practice round under their belts.

Different guys do it differently, but in the 30-or-so week-long professional tournaments I’ve played, one of the things I’ll do during my practice round is jot down in my course guide or on a scorecard how far my clubs are going on full swings. By the end of the round, I’ll approximate the percent difference from my normal distances and then make a new distance card that I keep with me for reference during the tournament.

For example, let’s say these are my average carry distances (pros are more concerned with carry than total distance) for my clubs on flat ground under normal conditions:

Club Carry
Driver 270
3-Wood 243
16* Hybrid 225
20* Hybrid 212
4-Iron 203
5-Iron 194
6-Iron 183
7-Iron 172
8-Iron 160
9-Iron 148
PW 136

 

Then, over the course of my practice round, I find out that on average I’m about 3 percent longer with each club at this new course I’m playing.  So I get out my calculator, add 3 percent, and then make a small card like this to carry with me for reference during the rest of the tournament:  Personally, I like having a little card like this because it saves me both time in determining what shot I want to hit and also mental energy during the tournament rounds.

Club Carry
Driver 278
3-Wood 250
16* Hybrid 232
20* Hybrid 218
4-Iron 209
5-Iron 200
6-Iron 188
7-Iron 177
8-Iron 165
9-Iron 152
PW 140

 

Note that on the updated card it’s only about a 4-yard variation for the PW, but that could mean the difference between having a 3-footer for birdie or a 15-footer.  With the driver, the 8-yards of extra carry might give me the confidence to fly over a fairway bunker I normally wouldn’t otherwise try to carry.

You may not want to get in to this level of detail with your own game (or have the ball-striking skill to worry about it – hehe), but I guess the point I’m getting at is to keep in mind that depending on the course you play and the conditions involved, distances can and will vary.

Understanding and accepting this can help you make better club selections in general, which of course can also lead to lower scores.

    Ruddy – Haha, yeah, especially on new courses it helps to pay attention right away. :-p

    Hmmm, if I remember correctly, Advanced Golf Solutions also tested the balls by accuracy. So you could pick something out based on any number of variables…distance, accuracy, price, etc.

    I think the ProV1x was the most accurate…or at least in the top 3. But that was a few years ago. Ball models change as time passes.

    They must’ve gone out of business because I’m not finding their website…which is too bad because it was really cool software. They tested the top 50 or so new balls on the market each year for several years.

    Jacob, thanks for answering. I too noticed a big difference in distance between balls. 10 yards less with Titleist Velocity vs. ProV1x. Better scores with the expensive ball, also. I never seem to recognize the distance variation each round until around Hole#18!

    Ruddy – Yeah, using the same model ball can definitely help consistency. I remember one time I did some new ball testing using some independent testing software (I believe made by Advanced Golf Solutions) and there was literally a 50 yard difference between the longest ball and shortest ball for me (that variance will be more or less depending on swing speed and other factors).

    I just do it as a rough percentage because during a single practice round I may not get enough flat shots (no elevation changes) without wind to get an average for each club.

    In situations where I don’t get in a practice round, I just try to pay really close attention on the first few holes and adjust up or down accordingly as quickly as I can.

    Interesting article. Averages are greatly affected by extremes, so good move to eliminate extremely long and short distances. The mode is the distance most often achieved. The median is the distance exactly in the middle. Rather than a percentage change, why not just use actual distance achieved for each club in the practice round? If I can’t play a practice round, how can I make a distance adjustment using some other method? I suppose using the same ball brand helps consistency. Thanks.

    Al, Mark, Steve…thanks!

    Good suggestion, Steve. Those things definitely do have an effect on distance. I know I’ve seen studies that have covered this but I don’t recall specifics or where I saw them off the top of my head. I’ll put it on my list of article ideas for the future!

    Happy New Year!

    Jaacob, nice article. I wish you would have spent some time discussing temperature and it’s effect on distance. Don’t golf balls fly further in the heat vs. cold air? What about in high humidity/fog, vs. dry air? Thanks!

    Very interesting Jaacob and well put together. All the very best for the Hols mate. Mark in Oz!

    Jaacob, I love your attention to numbers and stats, it’s right up my alley!

    Congrats on a solid first piece, and I’m looking forward to applying the playing and strategy knowledge that you relay.

    Great article, a subject that is hardly covered
