Pro rally net clearance?

It was during one of Federer's early round matches at the US Open this year when I though I saw a statistic that Federer's average net clearance on rally shots is 9"?
Did someone else hear the same thing?

sounds about right. He is not Nadal with 18-24” clearance. His shots are much flatter.

Here’s a good article and comparative on the subject:

Gosh, that seems awfully high. I did read that these are supposed to be based on statistics, just seems awfully high.

I'm watching Fed practicing court level - any opinions on average net clearance here? I would say on average 15".

I don't trust that net clearance data. 70 inches is almost as tall as I am. Meaning I could stand on top of the net and Fed wouldn't hit me with an average groundstroke? Ridiculous.

Just watch the first 3 minutes of this video and you'll see that it can't be true. There are some heigh shots in there, but even those don't clear the net by 60 inches. There are so many shots that only clear the net by a couple of inches, some net clippers in there as well. No way the average clearance is that much.

Based on ALL shots I think this would be accurate because there are quite a few defensive balls that would raise the average rally ball height a bit too. With net at center being 36 inches, I would think most are hitting around the 65 inch mark. Nadal a little more and definitely Murray less. Kinda what the chart demonstrats.

These numbers don’t account for the height of the net

It’s inches off the ground
That would mean Rafa clears the net at 4ft at the least. o_O lobs can't account for it that much. It still looks dodgy to me.
(Net height differs from 42" from posts to 36" at the centre.)

Seems to be about right. Nadal has higher net clearance than just about everyone, and they teach kids nowadays to clear the net by at least 3 feet

To me, while initially jarring, the more I pause to think about it the more the numbers make sense - the only way to hit as hard as the pros is to load it with topspin.

The more spin the better net clearance you probably need to go for because the slightest miscue results in the shot being dumped into the bottom of the net.

It’s no coincidence Fed and Nadal are often said to have the best forehands of all time - net clearance would be one reason that gets lost in the shuffle.

If I had the ability to generate the spin these guys do I’d aim well above the net too.

Off my own personal experience I vividly remember a day my FH was on fire - my average net clearance that day would have been 3+ ft. I felt like a pro.

But I don’t have the sort of confidence on regular days to aim that high, my topspin isn’t remotely good enough - the only way for me to aim that high and hope the ball stays in would be to slow down the swing.

I’d say watch a few of these pros practicing in person. You may see some things that surprise you.

Nadal bounce height at 56 inches is the most mind boggling stat. I don't imagine how I could even hit his balls (no pun intended).

And just when you’re done being mind boggled you see Federer avg bounce height 3 inches lower while having an avg net clearance 20 inches lower.

What these pros do is otherworldly.

I’d love to corroborate the information too. This is one of my gripes with tennis having no dependable data for how it’s being played at the professional levels.

Goes back into the issue of no value for compiling and archiving of information.

@Azure - above conversation offers a good example of how lacking tennis information is when we’re talking about how is it played.

Margin of clearance seems like one of the most basic things and yet here we are, there’s no data anyone can have confidence in.

I think the story in the link is saying that at the net the height of the ball above the ground is 90, 70, 63, 59 inches. Above the ground not the net. And net height is 36 inches. So net clearance is 54, 34, 27, 23 inches.
"Notice that Murray’s ball is the lowest at 59 inches. So even he has two feet of net clearance".
Basic story is pro ball clears the net at almost double the net height.

Yep, you need to read the article to process the above visual.

Aiming about 2 to 3 net levels higher is still jarring when you initially try to visualize it.

Of course they don't get to the calculation method for determining "average" One high defensive lob will skew the "mean" by a considerable amount. A "median" might be a better indicator of the average in this case as it will eliminate the lobs and the flat put away forehands and give you more of a rally ball indicator.
