GR translation: latencies

[Mike Jing]

V76.39-77.6, P78.21-28   Who can find his way about this lush maze of
initials, arrows solid and dotted, boxes big and small, names printed and
memorized? Not Ernest Pudding—that’s for the New Chaps with their little
green antennas out for the usable emanations of power, versed in American
politics (knowing the difference between the New Dealers of OWI and the
eastern and moneyed Republicans behind OSS), keeping brain-dossiers on
latencies, weaknesses, tea-taking habits, erogenous zones of all, all who
might someday be useful.

What does "latencies" refer to here?
