There is something deeply frustrating about colleagues using data from the Gorse Fox's spreadsheet without understanding its derivation and therefore its meaning.
The Gorse Fox was challenged on some numbers - and on realising where they had come from, had to point out that they could not be used in the way they had been. Unfortunately, they were the numbers that were now working their way through the system. The Gorse Fox then had to stay late and develop several other analyses that better exposed what was wanted - but didn't differ appreciably from what had been used above.
Only just caught the train as there were delays on the tube. Ended up leaping, gazelle-like, into the last compartment as the doors were closing... but it did mean missing supper, as it was too late to eat once home.
