It is impossible to cover all the great stories, but sometimes your correspondent just makes the wrong call.

On Tuesday, the diarist watched a guy from Edinburgh flash round a track and win a gold medal. The real story was, inevitably, elsewhere, where another Scottish legend was making sporting history. While I witnessed Sir Chris Hoy take his sixth gold, I missed Andy Cameron making a hole-in-one at the 11th at Cathkin Braes. Gutted.

The BBC has made great play of Yorkshire being well up the medal table. (five golds, 11 medals in all). But the diary's resident stats man says Scotland beats that. This nation has Sir Chris Hoy (two golds), Katherine Grainger (gold), Heather Stanning (gold), Andy Murray (gold and silver), Tim Baillie (gold), Scott Brash (gold). Luke Patience is guaranteed a silver and Michael Jamieson and David Florence have won silvers. Yorkshire's population is about the same as Scotland's at 5.2m. Incidentally, six golds and three silvers would put Scotland ahead of Australia, New Zealand, South Africa, Cuba and Kenya in the medals table.

It has been a good Olympics for Greggs.

The Tube carried a record 4.4m passengers on Friday. They were all in my carriage on the way to Stratford.

Call for a drugs test at London Bridge Underground. The station announcer sounds as if he is sucking helium after ingesting amphetamines. This, trust me, is never wise.

The Diarist has been awarded a commendation in the equestrian Grand Prix Special test. "That was a magnificent example of the piaffe," one official told me. The piaffe is a movement when the horse appears to be dancing on the spot in an elevated trot. This was performed by me in the extremely elongated queue for the public conveniences.
