In the diff you only change the -width parameter and not the actual .It line

As using delay, I have used it with delaying DNS traffic with this
snippet. I'm using no state, cause otherwise an existing state will
ruin my delay attempt.

pass out inet6 proto {tcp, udp} from any to port 53 no state
pass out inet proto {tcp, udp} from any to port 53 no state
pass in inet6 proto {tcp, udp} from any port 53 to any no state
pass in inet proto {tcp, udp} from any port 53 to any no state

pass out on egress proto {tcp, udp} from any to <google> port 53 set delay 1000 no state

# Delay list
table <google> const {
216.239.32.10
216.239.34.10
216.239.36.10
216.239.38.10
2001:4860:4802:32::a
2001:4860:4802:34::a
2001:4860:4802:36::a
2001:4860:4802:38::a
}

I hope I did not miss any other required line from pf.conf to make it
work.
