Intelligence strategy guide?

[unmerged(6006)]

Is there a 'guide' anywhere for using the new Intelligence options in DD? I'm thinking of something that offers some strategy pointers, like there is for most of the features of the original HOI2

I've been considering doing an "Is Espionage Worthless?" AAA/thread, to match my "Are Submarines Worthless?" and "Are STRAT Bombers Worthless?" AAR/threads.
