OK but, how did they figure out that they had precisely 3.3 tsp of baking powder? What kind of measurement device would tell you that? 3.25, yes. 3.5, yes. Because you have quarter and half tsp measuring spoons, but no spoons to measure a decimal portion of volume.
For baking powder, eye-balling a fraction of a teaspoon in that spoon is good enough for baking. Use weight instead (for all ingredients) if you want any kind of precision and accuracy; measure in grams to make scaling easier. Once you learn this, you’ll never want to go back to cups and spoons.
Tell the author. They were measuring in teaspoons and claimed they had 3.3 tsp.

You mean about the proportion working for all values? No joke. If you think about it, it has to work like that since the two scales are fixed. You set the relationship between them once and leave it in that position, then you are just looking at different points along the scale to see the corresponding number on the other scale. So 1/2 = 2/4 = 3/6 etc.
I remember when I was a kid my uncle had a slide rule and showed me how to use it. It was amazing how many different kind of calculations you could do. Of course I’ve forgotten most of what he said, but I remember how cool it was.
