What are the Ānāpānasati Kammaṭṭhāna as Taught By Ven. Kiribathgoda Gnanananda Thero

I am curious to know how Ven. Kiribathgoda Gnanananda Thero teachers Ānāpānasati. Does he follow the 16 stage instructions or perhaps something similar to the 8 step method1 or combination of both or something different with or without overlap. NB: In answering this please make this a self contained answer without having to navigate links and audio files. --- 1 Anapana Sati Meditation on Breathing by Ven. Mahathera Nauyane Ariyadhamma
