The significance level is determined by a formula used with the original zener card tests:

<1.96 = no psychic ability.

1.96 - 2.58 = some psychic ability.

2.58 - 3.00 = significant psychic ability.

3.00+ = very signficant psychic ability.

In a standard game of 25 guesses:

Advanced (15 - 19: 1 in 90,000)

Impossible? (25: 1 in 300 quadrillion)
