Gathering more than one progress data set separately is the only way to get a single data set. If you try a single measurement or combine them to early you will get [many] layers of people making stuff up and the further up you go the more nonsensical the data gets.
If someone has only half (or less) of the data to forge his lies out of the creative book keeping window is almost gone. Employees with 10-20 years of experience generate lies of undetectable mind blowing quality. I've seen people negotiate their way out of 100% of their job arguing they didn't have time for it.
