\caption{ICARM curves of rank $24$--$31$: number of curves on which each kernel certifies $\ran\le r$ under GRH with $p<10^{10}$; ``only optimal'' = certified by the optimal kernel but not by the fixed one; ratio = primes needed by the fixed kernel divided by primes needed by the optimal kernel, over curves where both succeed.}
