Yes, perhaps I am to some extent.
> Empirical evidence is experiential by definition
I would have said it relies on tangible evidence, material evidence. Its status as an experience by an observer, if present, is secondary. I say this because evidence can be gathered without anyone experiencing it directly. Consider Curiosity on Mars. If we read a mass spectrometer's results radioed back to Earth and draw conclusions on that basis, it's a stretch to assert that we've experienced the evidence. Its interpretation certainly involves an observer, but not the evidence gathering itself -- that is often automated, even here on earth.
> Ex. If God exists, then religious experience is empirical evidence of this.
No, I think a spiritual experience contradicts the direct, physical sense of empirical. I usually regard empirical evidence as that kind of physical evidence that forces different, similarly equipped observers into agreement on its meaning.
Example -- when the CMB was confirmed in the mid-1960s, it killed off the last hope for a steady-state universe. Until then the Big Bang's critics were theorizing that the universe created new matter between the galaxies, so even though the universe was clearly expanding, this didn't mean it had a beginning or an end. The CMB detection, which wasn't really anyone's direct experience, falsified this alternative to the Big Bang. And it's objective in the sense that anyone can set up and detect the same evidence using indirect means -- not by direct experience.
