Finding the correct formula is moot.
You have 3 springs in the first place because the masses are convinced they can defy the laws of physics and isolate an object from all sources of vibration simultaneously. If you're only trying to isolate against one source of vibration, which is it? And if you succeed isolating against that source, how are you going to deal with the other sources of vibration. It also helps to know which source induces the most harm.
In other words, considering virtually everything in this universe is one form of vibration or another, the attempt to isolate anything is impossible to achieve, though many die trying. Even in a vacuum chamber the object must be levitating to achieve complete isolation. Short of that, once resonant energy enters into or makes contact with the object, it matters not whence it came. Because now the unwanted energy must escape before it induces its catastrophic harm.
About the only thing the springs are good for at this juncture is to ensure all vibrations already captured within remain trapped so that they cannot escape but must dissipate within. Oh, one more thing. The springs will also ensure that they and the platter they sustain will vibrate in sympathy with the already captured vibrations, hence taking an already poorly engineered situation and making it worse.
Don't believe me? Of course not. Try removing the springs for a few days and replace temporarily with some hardwood or better yet metal blocks and then place your massloading weight on it. If you do, I can all but guarantee you'll never go back to the springs.
Actually, the springs do serve one other purpose, the very purpose for which they were probably introduced. If your 400 lbs. spouse likes to 2-step on your suspended flooring system right in front of your turntable, the springs may prevent the stylus from jumping 14 grooves and instead jump only 5 grooves.
Anyway, good luck with the leveling formula.
