Thanks for your hint, saving evaluation data as array solved my issue.

I implemented this using a standard ACF form group loaded from the single.php template and adding the following hooks:

1. Hook into acf/update_value and retrieve value:
   $value = get_post_meta( $post_id, $field['name']);
2. In the same hook overwrite $value as an array:
   $value[get_current_user_id()] = $value;
3. Hook into acf/load_field and retrieve value:
   $value = get_post_meta( get_the_ID(), $field['name']);
4. In the same hook extract value from array:
   $field['value'] = $value[0][get_current_user_id()];
