With 5% random random, there's 8% chance of not getting it in 50 tries. (1-0.05)^50 == 0.077. With 2.5% random (10% chance with four options, only one of which is the one you want), the chance of not getting that random in 50 tries is 28%, and 8% in 100 tries. Sometimes you just get unlucky.

There seem to be weird numbers thrown around sometimes, but they're very hard to test.
