Who is 'anchor 11' (pfctl -vvss ./. pfctl -vsA)?

Hello,

in the midst of debugging ruleset/migrations, I came across this output
in 'pfctl -vvss':
all tcp 10.45.30.7:993 (public-nat:993) <- remote-ip:4690
ESTABLISHED:ESTABLISHED
[1683650613 + 66296] wscale 7 [3702552199 + 16768] wscale 2
age 04:32:22, expires in 00:09:25, 745:737 pkts, 55579:87226 bytes,
anchor 11, rule 0, source-track
id: 5b5139707ff0259a creatorid: cfe3cb20

Now, who is 'anchor 11'? By no means 'relayctl show redirects' or 'pfctl
-vsA' or "pfctl -a 'relayd/*' -vvsr"
would give me a "numbered" clue. The anchors are ascii/literally named -
no number like on the
rules in 'pfctl -vvsr'.

In the current case I've only one relayd-redirection with port 993, so I
can guestimate the anchor.

Am I overlooking a pfctl/relayctl option or is '11' internal only?

TIA,
