To generate random values and drop the bias applied by fast-check you may want to add the
.noBias()on your arbitraries. Bias being more frequent for the very first generated values the[0]might be highly impacted by it. More at https://fast-check.dev/docs/core-blocks/arbitraries/combiners/any/#nobias
