You can certainly take your experience and reach such a conclusion. In a very specific price / equipment band it probably holds true.
I don't apply a formula to such things because there are always variations, but budget should always be generously sliced to allow the best table possible. This for me is a constant. If the tonearm or cart are more costly in a ratio sense so be it. For me it comes down to synergistic combinations...
I have a client using the STST Motus table. He has lots of arms and carts. One of his favorite combo's after trying many is an SME 312S and a Hana. Just a data point.
