"I.e. the strips tend to report a pH reading that is about 0.3 pH less than what is determined with a calibrated pH meter"
Ok, got that part. So above, when I read 5.8 with the strip, that really means 6.1? Still leaves what do I do about the temp? The ph at mash temp is supposedly 0.3 off from the ph at ambient. Do I add or subtract 0.3? Ultimately, I guess I want to find out how from the magical 5.2 I am so I can see which direction to adjust things, right?
