Question about the difference in my old panel's ground resistance after a full rework

The reading went from 25 ohms to under 5 after we found and fixed a single corroded clamp in the main water line bond, so what's the most common spot you all find a bad ground connection in older homes?

That "fixed" clamp is always the culprit.

Check the ground rod clamp itself...
