Since the AI isn't moving across the world as fast as the animation would suggest, first try setting it to a high number like 20. Then follow the Sid Meier rule and double or half it every time you make a change. Yes, but the AI only reads the value when it starts moving. After you change it in play mode, get the AI to stop moving and then start again. If you want. They'll just come back, though, if you update RFPSP in the future.
