Barnes doesnt allow you to change barometric pressure or humidity, they are defaulted at the standard.

Yeah, it wont let you adjust drag functions either. That was my first commercial calculator, hence the birth of The Reloader's Archive. It also lets a shooter fill the gaps between regular drag models (G1, G5, G7 etc...)to create his own personal trajectory. In most cases, the BC decay (drag function) and BC can be adjusted together in differant directions to get more precise drop charts. Most shooters who struggle to create an accurate drop chart find they can create one near perfect with TRA vs some of the other programs out there.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
