fix: Track parameter estimation might give inf time

[paulgessinger]

This popped up as a persistent test failure on macOS, but apparently not anywhere else. I think if we have estimated parameters here without a z component, the time calculated is inf. There's already a fallback caldulation in case the path length along z is 0, which I think we can reuse.
