The 20 days of consecutive reciting of each chapter is perfect, but I think the 30 days off is too many.  Going to rethink how this is all structured.  I think I’ll try 20-15-10–Twenty days of reciting a chapter, 15 days off, then 10 days of reciting it again.  Still on a learning curve.  My spreadsheets seem to be changing monthly but things are still going well.
