If you use all your AP in a day, it should yield you at LEAST 10 bones. Unless you use quartz/apples, we are looking at 15 days at least to get those bones.

Source: I had 0 bones, so I farmed bones 4 days straight during Fate/Accel Zero Order extension period and currently have 40 in my inventory.
