There is no answer specific answer.
Every region looks at it differently and area, topography, neighbours etc are all important....
EXTREME Example...
2 Acres in a Deep Valley with high sides all round and no neighbours for miles, you may even get a .5inch at 6000ish ft lb.
100 acres of flat open land completely surrounded by schools, housing estates, playgrounds, etc, fair chance of getting nothing!
i see what u mean well i got a gd bita ground then nothing for miles except hills
