The dry method in one of the tutorials, where you soak then squeeze out your brush before hitting the puck until the bristles clump together, has never worked for me.
I pre-soak, then shake the brush until no substantial amount of water is coming out but it is still a lot wetter than when you squeeze it and then I hit the puck for a good long while (it may take up to 2 minutes). At first the lather is thin and foamy but after a while it usually sets. I keep going, adding water by dipping the tips of the brush in water, until the brush is completely saturated with soap and peaks of lather are visible on the soap and on the brush. Last but least I face lather.
This might be more wasteful than other techniques and indeed to start off with the "proto-lather" tends to spill off the edges of the container but once your brush is fully loaded, you rarely need to go back to the puck and reload and since I am not using a lathering bowl, there is no supplemental wasteage.
As always YMMV
