ISS Solar Transit

It looks like ISS will transit the sun in Tuscaloosa, AL (33.206667, -87.534722) on Wednesday Dec. 13. The three tools that I've looked at show slightly different ideal locations and times for the transit. Who should I believe:

This may be obvious to someone who has already found three transit sites, but orbital calculations are not an exact science. I mean, the physics isn't uncertain, at least at the level relevant to humans. But, there is uncertainty in the observations to calculate the orbit, and these observations can be averaged in different ways. The path of the sun is really wide, so unless someone who really knows their solar occultations chimes in, I would just pick one and not worry about it, unless you're trying to get a picture with the ISS right in the dead center or something like that.
