Right on point.
But, keep in mind that the soil pH is nothing more than a "quick-reference" for the soil condition...a view from 10,000 feet, if you will.

What soil pH really tells you is the presence or absence of hydrogen...nothing more. The base saturation cations, potassium, calcium, magnesium and sodium are the major players in affecting soil pH. When they are out of proportion, you can chase pH for years without success.

Rather, if you adjust the calcium:magnesium ratio appropriate to the soil CEC (ie 68%:12%) that will get the right air:water ratio into your rootzone first and create an environment conducive to microbial activity and the soil pH will adjust itself toward neutral.

Also, nitrogen applications rates must also be made according to the soil CEC to maximize NUE and lessen leaching risk.
