Is that acceptable (assuming it really is now hitting focus)? Or should I send it in to Canon for calibration?

If it's within the adjustment range, then you're ok. Each camera/lens combination will be different. Also, be sure to adjust for your TC/lens combinations (assuming you're using Canon TCs that'll identify themselves to the camera).
