One for reply_header_add, another one for tcp_outgoing_address. -> a random 1/5 of requests will have "Start: a" header added. -> a random 1/5 of requests will try to send from 12.13.200.10 IP address. The two sets likely do not overlap. Though since this is truly random - there is a 2.5% chance that any request might *look* like what you are seeking. To make the IP based on the "a" existence you have to ... base it on the "a" - not on some random number.
