Didn't mean to imply it was YOUR chart.
However, it's commonly posted here, even by me, but not always with a proper description of feeding duration.
While we are on it, adult (non-breeding) BP's should be fed every other week (every 2 weeks), IMO. I also think, unless a huge adult BP, small rats are fine for life. Even at 1,800G, my female BP skipped meals frequently on medium rats. She does great on small rats every 2 weeks.
