This might assist you with posting to a newsgroup, albeit through a website:
https://tools.ietf.org/html/rfc1855

- If you are sending a reply to a message or a posting be sure you
summarize the original at the top of the message, or include just
enough text of the original to give a context.

Especially when you specifically say you're 'replying' to Chris.

Is Chris still alive? His post was 13 years ago.

Better to start a new post rather than resurrect a very old one.

Perhaps you can read the old thread and tell us what the estimates were,
I doubt they have gone up very much?
