The math for figuring F & BW:
(D - U)/ 2 = F
(U + D)/2 = BW

You forgot to divide by 2.

Orig should be:  18  51
New                   12  45

Friction is OK with the new but the BW is still too high.
Seems like a drastic chance for just changing wips.
Were the old wip centers on the tight side?

What's the FW?
