I got blacklisted for MUCH less than half of those amounts. My server doesn't
go anywhere near 100,000 connections a day, or 300,000 queries a day. And good
luck getting spamhaus to reply to ANY e-mails asking about it.

If they decide to blacklist you, it will be arbitrarily below the stated
amounts, and you will never get an answer if you ask for how they arrived at it.
