When displaying Acres, a 1 sqft change shows up as 0.0000230 acres. So yes, you need 5 decimal places for that. A 2 sqft change will show up as 0.0000460 and when rounded to 5 decimal places will display as 0.00005. I’ve had surveyors in downtown dallas tx that display more than 5 because of the sqft $$ of land.
