Based on Amir Shakkar's story, what was Sai Baba's routine involving the Chavadi?

Chapter 22 provides specific details about Sai Baba's routine concerning the Chavadi. There was a daily component and an alternate-day component. Every morning, Baba would pass the Chavadi on his way to and from begging for alms. In the evenings, his routine included coming in front of the Chavadi, where he would salute all directions by moving his index finger and head before returning to the Masjid. The most significant part of the routine was that every alternate night, Baba would leave the Masjid to go and stay in the Chavadi. During these stays, after the Aarti and departure of devotees, he would have calm conversations with Amir Shakkar.
