Bad Data

I have a PhD friend who is a patent agent working for law firms. He mentioned he spends a lot of time telling applicants their data is bad. Data validation, especially hard to get even once data, is incredibly important. Doing noise investigation work in extreme environments I had a primary digital recording system, a backup digital system, and even a video camera with good audio recording capabilities. I used to buy inexpensive color printers to print out analyzed data onsite. Always come back with the data you are after.
