Hi General_Correspondence,
Thank you very much for your input; I've been a cost/price analyst for about 15 years, and, believe it or not, I've never heard of, or, used CALC.gsa. Neither had my colleagues (with many years experience). We are very excited about the prospect of this tool; and, we recognize that it cannot be used as THE sole data point; however, it will be very useful in conjunction with the other tools we employ; the more tools the merrier.
In fact, we are well aware of the fact that GSA cannot be used as the SOLE basis of determining a fair and reasonable price, Shay
