RE: to many hunters
Alot of variables that depend on hunter capacity on any given acreage.
I would say your 4-5 guys on a 170+40 = 210 acre farm isn't too many by any stretch.
1st and foremost is it shotgun or center fire hunting(distance from adjacent hunter(s).
Are there AG crops and/or mix of woods or bedding areas within the area.
Any good trees that produce mast.
Any state WMA's adjacent to property.
Any food plots on property or adjacent property.
Any ponds,streams,rivers,marsh run thru property.
How you place stands in relation to deer movement and prevailing winds.
Last but not least what kind of hunters on the property whether it be 2-10 or 100.Do they like to walk,roam,drink beer,make noise,come in late or leave early,stink the place up,and generally speaking - Are they Slob Hunters?
Answer all those questions and you've answered your own question on your particular hunting ground/lease/farm etc.. My .02
