Description
From diagram above it looks like that transition time from SYN_RECV to ESTABLISHED should be near RTT between hosts?
But my tests shows very low numbers:
SYN_RECV -> ESTABLISHED 0.015
SYN_RECV -> ESTABLISHED 0.017
SYN_RECV -> ESTABLISHED 0.051
TCP Fast Open turned off on host.
Is it bug or i'm wrong?

Research direction
The issue names no file, test, or entry point. Start by reviewing the TCP state-transition diagram and reproducing the reported SYN_RECV to ESTABLISHED timings with TCP Fast Open disabled; compare them with the hosts' RTT and determine whether the behavior is expected or indicates a BCC measurement bug.
