Conceptual question: When you have a super complicated circuit, does it matter which node you start at when finding equivalent resistance? How about capacitance?
Two ways to answer this question:
If the circuit is really complicated, you will be using a linear algebra or matrix solution method to solve it, not combining elements in any particular order.
If changing the order of operations in your method of finding the equivalent resistance creates different results, then one or the other of your methods (or both) is faulty.
