So computer makes the decision?
Or the information is gathered and a human being applies the decision still?

It is purely data driven. They measure a bunch of data for the whole league, e.g. for OF for a given distance from a player,angle and time they compile statistics about the percent of time a player catches the ball. Then for a given player they compare what he does against the against the overall data for the league. So if the league average is to catch a particular ball (eg a given distance,angle,time to catch) %75 of the time, and the player catches it, they get +0.25 credit and if he misses it he will get -0.75 credit. All of this then gets computed over a season for an overall score for the player. If a player ends up with a 0.0 score they are an average fielder, anything above 0.0 is above average and below 0.0 is below average.

The metrics used are different for IF.

Yes I understand those percentages. I could not find the miles per hour in the determining factors? But then again I did not read the entire article LOL

That would be a component of the time metric they are using..(harder hit ball would require less time and slower hit ball)

Referring to the mph #'s speeds.

Why do you need that to understand the statistic? Are you trying to figure out whether you would be an above average OF in MLB?

Again, for every ball hit in the OF, the time, distance and direction are measured along with whether the ball was caught. From this a probability distribution is constructed. This is then used to assign values to individual plays for players.

The question was simple. Then backbiting other people's success is completely unnecessary.

The question was
A SIMPLE QUESTION TO THE TOPIC OF
identifying the mph specific that
****changes the Judgment of making the call.****

No need to berate you because you missed that. That's a hint.

The question was simple. Your interpretation of the follow-up post has gone awry.

The question was identifying the mph specific that changes the Judgment of making the call. It's unfortunate that when you can't understand.

There is no judgement. It is purely data driven. They collect data, build a a probability distribution and then use that to attach a number to an individual play. It is all done with a computer. The measured ball velocity is factored in the time variable in the probability distribution.

You had said previously they measure the speed of the ball. What was that speed. Apparently it's not part of information shared????????

I don’t know if they actually publish any of the information tbh but if they did only the time (which would have been calculated using a measured batted ball velocity) , distance and direction would be given since those are the variables used (for the OF calculations) MLB does publish exit velocity stats in general.

I wasn’t throwing stones or backbiting your success (it was a joke..) I just didn’t understand (like you said) why you wanted that information as it isn’t relevant in understanding that defensive metric.

 

[radness]

it isn’t relevant in understanding that defensive metric.

Agree not relevant to understanding that accumulated data is used for defensive metric.

However the #of mph is relevant to the detail how that metric is measured.

As an example people measure bat speed. if all they talked about was bat speed without offering the actual
# mph it is a conversation without detail.
