Not quite correct, if I remember correctly dry soil adsorbs more water and quicker (by default) than waterlogged soil. But when is been dry for a long time a hydrophobic film forms, causing a temporary delay in water adsorption. I think it can impact flash flooding, but it washes off fairly quickly and then adsorption returns to expected.
Just latex to svg your math for impress.
For real though, it’s such a miss for impress to not have in line math
