Populate field value with value of a different field?

I need to dynamically populate the default value of a field named “contact_info” with the value of a different field called “center_address” on a different page. I found code for populating the default value dynamically, but I can’t seem to get it working. Can you tell me what I’m doing wrong with the below code?

$address = get_field('center_address', 342);
	
add_filter('acf/load_field/name=contact_info',
     function($field) use ($address) {           
	     $field['default_value'] = $address;
	     return $field;
     }
);

I tried using the_field instead of get_field, but that didn’t work either.

This code is in functions.php. I’m trying to target a backend form on the post editing screen. The fields are text fields. I am using ACF Pro.

I appreciate any help!

Nevermind! I figured it out myself. I needed to format it like this:

function my_acf_load_field( $field ) {
		
     $address = get_field('center_address', 342);
		
     $field['default_value'] = $address;
     return $field;
		 
}

add_filter('acf/load_field/name=contact_person', 'my_acf_load_field');

However — it brings me to a new question. Is this super resource intensive? This contact_person field that I’m populating is present on a LOT of posts.
