Please forgive the "stupid questions" here...
If you measure the tower as though it's completely unloaded, then use that
for the modelling software... does it not then throw the modelling out the
proverbial window as soon as you reconnect all of that other "stuff"?
Would it not make sense to measure and model it both ways, so that you can:
a) see the difference, and
b) see what it will do in reality?
