not a weekly release in japan, if i remember i didnt see too many releases while i was in japan. therefore its a monthly release or hes just does it whenever he feels like it. each race takes easily 10+ chapters to complete. the manga focuses on everyone, the anime mostly on the ae86. also think that each chapter of the manga is roughly 15 pages of art. this is 18min of anime which would take a lot of pages to complete one episode.
