Saving BP tome 10 level 2

I have 2 different paths depending on what you choose to do:

Scenario 1:

This way saves you a total of 345k BP, however, the top right of the tome is quite mean and designed in a way that hurts people who save BP.

I did another path for those that want the most bang for their buck as they say:


This way saves you in total 355k bp, however the challenges at the top right remain incomplete. Typically (you never know, don't take my word for it) BHVR releases chapters about a week before level 4 of the tome comes out, so there is usually a week before anyone gets any new challenges. I'll just be doing the challenges that are not done when the Ringu chapter comes out, which will net another 85k bp for a total of 440k saved instead of 345k in the first photo.

Let me know if that is confusing or if anyone finds a better path.
