Based on Polkajam choices here for tiny which holds W_G=4104 constant from GP's full:

Image

we should adjust V of the 6 configurations (small, medium, large, xlarge, 2xlarge, 3xlarge) based on the factors of 4104 that are multiples of 3 (since V=3*C):

  • 6 tiny (C=2)
  • 9
  • 12 small (C=4)
  • 18 medium (C=6)
  • 27
  • 36 large (C=12)
  • 54 (C=18)
  • 57 (C=19)
  • 108 xlarge (C=36)
  • 114 (C=38)
  • 171 (C=57)
  • 228 (C=76)
  • 342 2xlarge (C=114)
  • 513 (C=171)
  • 684 3xlarge (C=228)

The following diagram shows the erasure coding from tiny to full:

The $W_G$=4104 segment size is essential as a constraint for CoreVM-class services to have refine processes basically store the commitment of several thousand VM 4096-byte pages within the availability specifier. W_P and W_E follow directly from V.
