I make pour over the very first thing early in the morning, usually while an 8 month old baby is crawling around chaotically. I just put the ceramic dripper on my mug, pour a bit of water for the bloom without "timing" it, then pour some more like three times until the mug is full. Yeah I use a gooseneck kettle (which btw also comes in handy for watering flowers and filling up the clothes iron) but I'm not fussy about technique. Occasionally I just dump a bunch of water in the filter at once and the coffee turns out fine if a bit weak.
I have a Chemex three cup and I can make one or two cups with it without any timer or scale. It tastes great to me and is really consistent. The need for scientific exactness is overblown here (although using a scale and timer only helps the result). Even a bad brew from my chemex with freshly roasted single origin beans is far better than the terrible black coffee I drank at the office for years (and still will drink if it’s all that’s available)
