I'm not an English major, but when I started with: "It sounds to me like you need a different data structure, a HoA (Hash of Array)", I reckon, "It sounds to me" implies some amount of uncertainty.

I don't see a problem here. You are actually paying me a compliment by telling me that what I say does matter! I will strive to be better, but as a practical matter not every post (if any!) I write will ever be "perfect". I am not perfect, but I do try to be helpful in a constructive way.

Software is devilishly tricky because there are "the heuristics" and then the exceptions to the "rule". Its a situation where in order to "break the rules", you have to know what the "rules are" and why they make sense, which I think goes to your point.
