the test

fails if the value
p

falls outside the interval (p

p

) ⊂ (0, 1). The sequence

is considered suspicious when
r
or more test iterations failed.
Threshold testing for the VS generators was done with the following variable settings:
- ten iterations (K=10)
- the interval (pl,ph) equal to (0.05, 0.95)
- r= 5.
The chance to reject a 'good' sequence in this case is 0.16349374% ≅ 0.2%.
