so we are starting.

add_action('init', 'wpaccuracy_callback_run_me_early', 9);

The first function run will be wporg_call_backrun_me_early(), because it has a manual priority of 9

add_action('init', 'wpaccuracy_callback_run_me_normal');

Next, wpaccuracy_callback_run_me_normal(), because it has no priority set and so its priority is 10

add_action('init', 'wpaccuracy_callback_run_me_later', 11);

Next, wpaccuracy_callback_run_me_late() is run because it has a manual priority of 11
