I think it’s the right way to do it.
As they release the info in drips, the evidence builds on itself and it gives the general public the ability to absorb it in bites. (How do you eat an elephant? One bite at a time.) And we’re dealing with an elephant of evidence.

It also, as Rudy pointed out, makes it virtually impossible for the left to counter with lies and misinformation because they have no idea what the next bit of information will entail.

This is like the snowball rolling downhill getting bigger as it does.
