Well, the idea is not a slow steady drip drip drip. But rather to add just enough saturate the grounds, then wait 30 seconds to a minute for the grounds to "bloom". Apparently that's a real thing, and one can sniff the aroma the "bloom" releases. I did some more reading and according to more than one site, the bloom is the release of CO2 trapped inside the beans. Although darker roasted coffees probably have less entrapped CO2, and one site says that coffees that were roasted more than a few days ago have probably lost most of their CO2 anyway. Personally I think that IF the bloom time is important, that CO2 release is just a symptom of the bloom, and like I conjectured earlier there may be other things going on with the coffee grounds. One site maintained that the coffee grounds need to be stirred gently during the bloom time. This helps to settle them, and the heavier ones sink to the bottom of the filter, helping to prevent clogging by fines. Also, without the pre-wetting and stirring, the grounds will tend to be more buoyant and float to the top of the filter cone or basket, not getting extracted as much.
I also found a discussion of french press methodology, and some maintain that one should add the water in a similar manner: a small amount, stir, wait a minute, then add the rest. I have noticed that in the french press there's a fair amount of buoyant grounds and foam when I add the water all at once. Haven't tried the pre-wetting technique with the press as yet.
I did try prewetting the grounds with the Scoop coffee maker. I simply used some of the pre-heat water to do that. I may experiment and actually pre-wet the grounds in a separate little vessel, let them sit a bit, then add the slurry to the filter and proceed with the regular drip process.
The pre-wetting of the grounds may get confused with the pre-wetting of the filter. Different purpose with the filter. It's supposed to clean it up, get rid of any paper taste, get rid of dust, and also preheat the basket/cone/receptacle. Since I'm using metal filters instead of paper I don't care much about getting rid of the paper taste (never have detected it anyway), but I think it helps to preheat the works before starting the regular drip process.
I know it all sounds complicated but there are some people who have put a lot of time and energy into brewing coffee just so, and their findings/opinions can be fascinating. Plus I have another week off work so I have time to play around with this stuff. It's not costing much except maybe getting me a bit more wired than usual, LOL.
Still not sure I want to try buttered coffee, though.
Here are some interesting links about the current coffee fad of "pour over" and how to do it...
Basic pour over technique:
Pour It On If you’re looking for a great cup of coffee that doesn’t require a lot of expensive gadgetry, a pour-over brewer, or manual cone filter, can be a perfect option. Here, Batdorf & Bronson coffee pro Jason Dominy shares some simple tips to ensure pour-over perfection. 1. Get soaked...

And this guy, coincidentally named "Richie", has taken pour over to a whole new level, impressing an astrophysicist with his methodical study of how to hit the "sweet spot" with each cup...
I guess part of my fascination with all this is that it makes me a bit nostalgic of my science research days. I sort of miss being able to plan an experiment to try to isolate one variable and figure out what the best combination and technique might be. Seems to me that the perfect cup of coffee would be far less elusive than a LOT of the bio projects I was assigned... and you can consume the results!
