Example A90 is an extreme example, because the result is very close and there are no strong candidates. For 60 of the 66 examples in Tideman's database, the runtime to calculate the Schulze STV winners is below 0.1 s. For one example (A17), the runtime is between 0.1 s and 1.0 s. For four examples (A03, A05, A35, A67), the runtime is between 1.0 s and 10.0 s. Only for one example (A90), the runtime is above 10.0 s. Markus Schulze
