I don’t know, weighing my coffee three times a day doesn’t seem too appealing. Using scoopes is fine as long you tune in your taste with the scoop, but you have to try to scoop consistently.
If you buy only one type of coffee and it's consistently the same roast level, then there shouldn't be a huge difference if you measure accurately.
But for me, I buy a different coffee bag every time and one scoop of a light roasted Ethiopian coffee will definitely not be equivalent of some darker Guatemalan coffee for example.
You don't need to measure it thrice though. Just measure the beans before grinding them and then calculate how much water you'll need. I also use the 60 grams of coffee per liter of water, ie 16:1 water/coffee ratio as a starting point. Then just measure the water with a scale or by volume.
It’s basically what I do, and also sometimes it isn’t perfect but I don’t expect it to always be either .
