No central obstruction, allow unequal forces on support points

No Central Obstruction, Variable forces on Supports

As pointed out by Nils Olof Carlin in this thread on Cloudy Nights, computing some of these cells while allowing for unequal load distribution on the support points might yield better results. The following simulations illustrate this, and can be compared to the simulations from the previous section.
