It means you've built four guitars with different body resonances.
There isn't any one "ideal" body resonance for classical guitars, and there are great guitars made with body resonances anywhere from below low E up to G#. The body resonance does perhaps determine the overall character of the guitar - if you like deep, warm basses, you're likely to prefer a guitar with a body resonance below F#, but if you like bright, strong trebles, you'll probably prefer something higher, but there are no absolutes.
As a maker, I think it's important to work out what sound you're looking for, and then try to be fairly consistent in how you build (at least for some time), and the body resonance is one measure of your consistency. If it's varying by more than a tone from guitar to guitar, then you're not really there yet. Of course, if you don't know yet what you're looking for tonally, then you probably need to keep changing things around for a while to see what happens.
