One habit that pays for itself: post the method alongside the number.

Thank you for spelling out the reasoning rather than just the conclusion.

Adding the clinical framing, because it changes how the question reads. Order of operations matters more than any single choice here: establish a baseline, change one thing, wait long enough for it to express itself, then measure again under the same conditions.

Moderator note: a post naming a supplier has been edited. Discuss suppliers in the review sections, not here. Carry on.

Adding the part of the answer the thread has not reached. The mechanism and the magnitude are separate questions. Agreeing that something happens says nothing about whether it happens enough to act on.

Adding the numbers, since they settle part of this. Keep the original post as written when you update it, and add the correction underneath. An edited-away mistake is invisible to the next person who makes it.
