BUt I have NO idea if it's a good analogy, I am an amateur here, I am just using the limited knowledge I have and a healthy dose of common sense.

The ONLY way to measure something like the speed of gravity, would be to have a difference to measure, and since the earth is at a set distant from the sun at all times, measuring from that relationship, it would seem to me, would be inaccurate, and a waste of time.

"since the earth is at a set distant from the sun at all times, measuring from that relationship, it would seem to me, would be inaccurate, and a waste of time."

You do realize that NO ONE on this thread disputes that the Sun itself is MOVING at 157 miles per second, correct?

If the Earth adjusts its orbit nearly instantaneously to the Sun's movement, how fast would Gravity have to be traveling?

We *can* measure where the Sun was at a set time in the past versus its position in the present, after all. Is the plane of the Earth's orbit going around the Sun's position in the past (which would indicate a certain delay in propagation), or is the Earth's orbital plane centered much closer to the Sun's actual present position?
