Oh no worries.
As a matter of fact, I didn't actually ban the guy... another mod did.
One thing I will say on the record is that me being a mod isn't something I'd ever want to use just to get the upper hand in an argument over grow styles/information- I'll sit here and argue with anyone, lol; as long as everyone is polite about it it's good, and everyone can learn from both sides.

Now back to your other question of the water in vs water out thing.
It's something you need to get a feel for.
Say your tap water is 7.
Your runoff from an initial flush is 6.5.
You can then assume that the true pH of your soil is actually a bit LOWER than 6.5, and you will want to bump it up a bit.

When you have such a large discrepancy between where you WANT your soil to be and where it actually is, it will likely take a few tries to get it stabilized at the proper level. So after the flush/adjustment, let the plant chill for a while, let the soil dry out a little, and next time it needs watering, check once more and adjust again if you need to.

Fixing the pH of bad soil is as much an art as it is a science, lol. That's why I like my humus! Buffer = 6.8-6.9.
