Now combine this with the % of soup remaining in a bowl once it has been tipped at its critical angle;  ostensibly no soup escapes the rightmost column before the container tips over, while almost all soup would have already escaped the up-left-most container.

Using this perhaps we can determine the optimal tip-to-spill ratio in a container

Then we see how the critical angle changes wrt amount of soup remaining in a container.
