61 volume for 616 pills equals approx. 1 volume for 10 pills, not 100. It may have been 100 or 200 pills per 1 volume at some point, but the last I played (weeks ago) it was 1 volume per 20 pills. I guess it’s now 10. Still, I can’t be sure if that’s intentional or not. Seems bit harsh and unrealistic though.
