Simplify Brewer Misc pourover by Bathtub Coffee

Bathtub Coffee's own method, and the argument the brewer was built to make: one pour, straight down the middle, and nothing else. No bloom, no circles, no stirring, no swirl. The 40 mm hole and the flat bed are supposed to do the evening out that the hand usually has to.

Notes

Bathtub gives the water only as hot; 95°C is what both Kurasu and Eight Ounce use when they publish this recipe, and Eight Ounce describe the cup it makes as delicate and tea-like. The technique here is a prohibition: aim the stream at the centre of the bed and keep it there for the whole thirty seconds. Rinsing is optional in the maker's own wording — it warms the brewer and pulls the paper taste, and skipping it changes little else. Everything should be through by two minutes. Past that, grind coarser; under a minute and a half, finer.
