Sounds like a nice idea.  However, I think that your values have a
flaw.  I think it should rather be

    2
    3   2*3/2

    4
    5   4*5/4
    6   4*6/4 = 4*3/2
    7   4*7/4               <===

    8
    9   8*9/8
   10   8*10/8 = 8*5/4
   11   8*11/8
   12   8*12/8 = 8*3/2
   ...

to be algorithmically derivable.  Maybe the user should be able to set
up exceptions, but this might need a lot of changes.
