If I am hitting with a significantly weaker player, I practice timing.
Focus on slow deliberate movement, timing, and strokes. Slow yourself down 50% in all areas. Turn your strokes into shadow strokes.
Even if you hit with 4.0 or 4.5 players, you need to be able to adjust timing to meet slow/medium paced shots as well as fast-paced shots.
