Something that I learned when I owned this post was that if your shock pump has ingested any fork oil in the past, a small amount can be transferred to the seat post when airing it up, and it will eventually contaminate the friction surfaces inside the post on the mechanical brake it uses to lock in position. The result is that sitting down hard on the post can make it let out a squawk and drop an inch or two. I eventually passed along the post because of this. I weigh 140 pounds, so I don't think that was the issue.
