This will not actually yield the competition bridge dynamics. How much it is off will be situation-dependent. In short though, you're now using spring force (F=-kx) rather than distributed bass to balance the moments. This means that, while you may pass the battery test,
as your bridge moves, the moment caused by the spring force will not fully mimic what the simply heavier competition bridge would do. It probably won't affect your bridge lowering tests, but if you're practicing (much less autonomously programming) balancing on it, don't count on the results being the same unless you've tested it.
