Regarding the "WR:"
How was this mistake even made?
Is it really that hard to figure out? Humans do these things, and humans make errors. You guys all saw this as Bob was inputting the results. The system does not let you input it all, proof it, the make it live. It is live as he starts to input the data. He inputs it, sees the error, makes the change.
There was an error in the file. These things happen. They have happened before, and will happen again. With so many times in a worksheet, with few people trying to do a lot of things in a short period of time, you will find the odd mistake. Perhaps people should be a little more patient with the process. But i guess the internet doesn't work that way. Someone always wants to claim, "First!" as if it makes them significant in life.
