I am not sure I understand your logic or the point you are making here, but if the tent you have is as good of a tent as the venerable and well tested Timberline you should be fine.

There may be a time where site selection may be critical. We had a cheap tent and generally picked a site where there was some shelter from the wind, but never the used extra guy lines, only perimeter stake. At one campground during our Trans America the tents all looked like a homeless encampment. Expanses of blue tarps and duct tape were everywhere patching up broken tents. We didn't give it much thought until the sun dipped below the horizon and the air immediately started flowing down the canyon. The clothes all blew off our clothes line. We barely managed to get the tent down flat and laid on it to protect it. We decided to try to move to a better site. All of the sheltered sites were taken, but we managed to get behind a low rise that directed the wind just enough after the worst of it had died down a little. We managed to find most of our stuff that was scattered pretty widely. The wind went from zero to crazy in seconds.

I bet a 2 man timberline properly pitched would have handled the wind where our 4 man dome tent failed miserably. There is a reason it is still being made and sold after what must be half a century.
