COFFEE BREW PLANNER

I am in my homebrewer era at the moment, so this is one of my stuffs: a small tool I made for daily use because the coffee calculators I found online did not quite fit how I brew. It helps me plan what is left in the bag, pick a practical dose, and generate a Tetsu Kasuya 4:6 recipe without overthinking the math. Mostly for me, but maybe useful if you happen to need the same thing.

BAG DOSE PLANNER

If the next brew uses 14.6 g

Then 14 brews remain at 16.8 g each.

That is the adjusted dose after spending one brew differently.
