Velocity vs accuracy

[daywalkerdad]

It's an interesting question and there's a lack of understanding of how radar guns work. I have parents say "She's pitching 50mph from 40 feet but it's much slower at 43 feet". Well no, not really. The radar will show you the same speed at almost any distance, as it captures the highest speed the ball goes on the flight of the ball. Which is at release. A girl's pitching speed doesn't drop when they go from 10U to 12U or 12U to 14U (as they move further from the plate).

Yes, the ball is going slower when it crosses the plate. But that's not what the radar gun captures. Well, not the under $500 ones. I think the Stalker ones can give you "release speed" and "over-the-plate speed".

It depends on the gun. When Nolan Ryan threw 101 it was 8’ in front of the plate. In the early 90s it got better, remember when Fox first did baseball they had a faster gun? It was picking up the ball closer. Then in the 2000s they got a gun that was within a few feet of release. Now statcast gets it right off the hand. They went back and adjusted old ones as the get closer to the release.

The Fastest Baseball Pitch Ever Could've Burned a Hole Through a Hitter's Bat

396 milliseconds. That's how long it takes for a baseball hurdling through space at 100 miles per hour to travel the 60 feet, 6 inches from a Major League Baseball mound to home plate. On average, it takes the human eye between 100 and 400 milliseconds to blink. You know that saying "in the...

It is hard to believe Ryan would be 106-107 if measured today.

Our hitting instructor wants to put both of my daughters on the Rapsodo next week. She said it is very good for softball hitting but is way behind for softball pitching compared to baseball pitching.

Maybe , Ask instructor why she commented that

Let me recap the velocity average “discussion” . Stats (not opinions) were given taken by an expensive machine which only serious pitchers are likely to use which were likely taken all over the country. You stated you thought those averages were on the low end because of what your single set of eyes have seen and you are backing up your claim by stating that in your opinion the average pitcher in CA is comparable to an average US pitcher.

Did I get any of that incorrect?

Lol...your funny .... simply prompted discussion talking about defining velocity speeds ( that's all I did) and brought perspective just like everybody else has brought theirs.

never said anybody was wrong

It's funny how you get

Have you ever changed your opinion on here when presented with information which goes against your original train of thought?

Having “discussions” with people who never change their mind is pointless ,annoying and a waste of time..might as well talk to a brick wall. It is why I make a point of never talking politics with anybody. Perhaps I need to widen my net in that regards..

In this case DATA was given..I cannot see how you can argue against it unless you are assuming bias (or insufficient sample size..which is possible I guess) in the sampling in which case you need to give a reason for why you think this bias would be present.

I honestly don’t care if the average is 100 mph for 10u..but I am not going presume my N=1 experience is more accurate than data unless I am given reason to..that’s hubris.

Yes, you have two people that watch a lot of softball (and clock a lot of pitchers at various levels and talk to others that do the same) that think the Rapsodo numbers are low relative to the characterization on serious pitchers. You also don't have clarity on exactly the sample that Rapsodo data represents (assumption that it is serious pitchers and not counting warm ups, experimentation, etc.)so you may suffer from the same bias you are highlighting. So now you have two opinions from CA based on nonrandom samples. The chart rad posted about averages and high end averages is more accurate and yes, that's my quasi subjective opinion. Backing away from the glib response though, most of the differences in this thread come down to sampling. We have opinions on everything from top tier power 5 to D1 to rec ball and across ages and geographies. I suspect there would be more agreement if definitions were precisely pinned but it's a forum and what fun would it be without a little pot stirring.

I stated that the data could be bad..but I am pretty sure that the observations of a few individuals is probably less reliable…

With regards to clarity, there is no lack of it imo. We are talking about ALL pitchers in a certain age group which makes it hard to believe that any one person’s opinion is viable. Even if it were TB only, still no way one person could have a good handle on it if we are talking the entire country or even only CA for that matter..

This isn't about knowledge,expertise or experience, Rad has those in spades. It is about the ability of one person to view, and process, enough radar numbers (even if the "sampling" gives a good representation of the complete population) to make their observations statistically significant.

Another Wrench for Data pile. No human is clocking the speed of the backup pitchers on the bench. Rapsodo records the data from non starters and less used pitchers.

Hmmm possibly you're not recognizing or not wanting to recognize the point that was made.
And/or
This is where you're digging into your own pit of nothing. Because you're avoiding recognizing the point that was a made.

LOL lighten up!!!

Think you're not recognizing or not wanting to recognize the point I was making.

This is where you're digging into your own pit of nothing. Because you're avoiding recognizing the point that was already made.

Remind me of the point you were making? Seriously.. not being a wiseass.

Seriously lol.....
You not being a wise rear I don't believe it LOL

This is an old topic that gets rehashed over and over it was fun for a while but now I'm going to watch a movie.
