I'm pretty sure my iPhone could have tracked that dog.

The iPhone certainly can, with everything in focus with the small sensor.

The X-T1 can AF track a fast moving subject better than the previous Fuji X cameras... just not well as the fast dSLRs--performance wise.

I'm finding the success rate of having frames in focus from the X-T1's AF-C is very dependent on the lens being used and the distance to subject.

Probably the AF sensors have aperture (different) specific sensitivity. What I mean is that the center point is say sensitive to f2.8 but with a non constant aperture lens like the 55-200 this will not be utilized and may fall back to f5.6. This may explain your findings.
