If you are not going to comment inline or bottom, then don't quote the previous post(s). You won't be top posting or bottom posting. Delete what's not relevant.

I do most of my reading from google, which collapses quoted material usually.
Did you actually read the Q&A I gave you? It is not an issue of where the cursor is when the news reader opens the post.

I'm not offended, just annoyed. I posted that pithy dialog to train new users. You obviously are stuck in your ways.

You also seem to still get confused, since the credo about not responding to top posts is not mine. Still think top posting is working for you?

What do you mean by "hotspot"? Oh, never mind I really don't want to know. You never answered my question about what is the business requirement for error margin. A vague "real-time" status doesn't cut it. (I've done real REAL-TIME programming. This transaction rate isn't it, at least not in the way you presented it.)

Well you have made your choice. All I did was point out it is not a good choice, IME.

Good bye.
