for(k=1,100,for(c=0,50,CEk2c(k,2*c+1,100))) : there are only 13 pseudoprimes out of 5588 numbers verifying the test; including 5575 primes: 0.23% of pseudoprimes. Out of a total of 125,000 numbers N tested.

For c<0, there are 1.22% of pseudoprimes (72 out of 5866 numbers verifying the test, including 5794 primes). Out of a total of 125,000 numbers N tested.
