The higher numbers will never come from LinkedIn spamming you to say you can make $x - the best jobs aren't and have never been on the market; they're the result of connections and referrals, because that's the only way you build enough trust.
I agree with you; it is my experience too, and I don't think my comment is incompatible with your reply. I was merely saying that the LinkedIn spam is roughly where the peaks are. (Large emphasis on "roughly".)
Edit: it occurred to me that I left the definition of "peak" unspecified. By peak I mean amounts with the largest amount of respondents, not the highest dollar amount.
