Another route is to not try to keep up with all his scholarship. If you track and read all his journal articles in the last couple of years, for example, you will find a lot of repetition and overlap. IMO it is far better and more fruitful to diversify one’s reading. There are scholars who publish less but to me appear to have thought more deeply about the content. In some senses, Analayo is basically a great compiler, a sort of modern-day Buddhaghosa.
I’m not sure ‘size’ is that relevant
