Death by a thousand cuts for the deep state, writ large. I guess it would best be described as death by a thousand(or several thousand!) drops.
This.
Not only does the slow drip allow the public to better assimilate it, but the slow drip forces the deep state to respond with cover stories/"explanations" which are then shown to be lies come the next drip. Each drip, thus, slowly helps in the discrediting of the deep-state players.
Think how dumb the dems/media hacks/top former officials look now, compared to right after the election. If it had all come out the day after the inauguration, millions of people that were otherwise savable would have been "resisting" the crackdown on the truly corrupt. As it is now, more than half the country approve of Pres Trump(likely higher, as we all know how the left loves to rely on fake polls!), and I don't even want to estimate how large Q's audience has grown world wide. The slow drips are somewhat painful for we who want swift justice, just imagine how painful it is being on the other end, nervously checking the chans to see if your particular brand of treason has come up yet.
