Yes. My experience is that my performance is evaluated via a spreadsheet that calibrated me against others on the team/dept. Spreadsheets are commonly used at most places. There are errors in some. However, I think the bigger errors are in the systems they represent rather than strictly in their implementation. Also, stale data is common since many people manually update stuff and aren't diligent about it.
