My only suggestion is that you are overthinking the pH thinking that the runoff number is the one to shoot for... it is not. Adjust your pH to 6.5 every time... and your soil pH will drift upward from there as the container dries out. You want your pH to drift between the 6.3-6.8 range every time... and watering at the proper pH is the key to making this happen. At the lower pH that you are adjusting to, there is a good chance that you will have a problem with magnesium being locked out... study this chart to see why.
