Chuck a macro in as well. That's a good way to check the maths. Good work.

Good point.

i skipped the macro as it is a prime lens. But you are right, focus breathing is not limited to zoom lenses at all.

Therefore, the updated table:

Adde the 60mm macro, as expected, it is the new number one in our little chart

From the numbers,the macro lens seems to have 22% focus breathing.

But a quick focus test is showing me that the background is growing 30% when I focus from 30cm to 10cm. This would be -30% focus breathing in our table, isn't it? Confusing ...
