Beck's second law: if you change from District to Piccadilly at Barons
Court Westbound, at least two Ealing Broadway trains will reach Acton
Town before an Uxbridge train turns up.

If you don't, one will overtake you.

Beck's Third Law: If travelling from Baker Street or Finchley Road to
Harrow-on-the-Hill, and the next two trains are an all-stations
followed by a fast, whichever one you don't take will arrive at Harrow
first.
