Good summary, and the caution about not self-diagnosing from a single reading is the right instinct. Isolated diastolic hypertension is genuinely a bit of an edge case in the guidelines, since most cardiovascular risk research is built around systolic numbers, so it's easy to find conflicting takes online if you're not going straight to primary clinical sources like ACC/AHA or ESC guidelines.
On the academic writing side, since you're compiling research like this into structured content, this is actually the same discipline a wikipedia page creator relies on daily: pulling from verifiable, reputable sources rather than tertiary blogs, and being careful not to overstate a claim beyond what the underlying data supports. Same rule applies whether you're drafting a paper or building a page meant to hold up to scrutiny.
