Maybe...
You might have read a post and hit reply. While you were replying, another person was already replying and posted slightly beofre you. It looks like a "post jump", but it's not.
In your example about reading and replying to my post about flaming and then I had a post before yours about the college experiements, I had both of those in one post. But, before I posted it, I CTRL-Xed the experiement part to put in it's own post. So, I posted the no flaming one and posted the experiement immediately after that....probably while you were posting your response about flaming.
I've been looking at the times, but I find no examples of the listed times as being out of chronological order. Can you show me an example?
BTW, whether a member flames or not is not dependent upon another member flaming. In other words, being flamed is not a reason to flame.
