A little PHP function to generate a delay that is between 0.1 and 5 with an average of .47 over time.

delay.php

    private function delay(): float
    {
        $quicker    = array_fill(0, 50, .1);
        $quick      = array_fill(0, 50, .2);
        $average    = array_fill(0, 60, .5);
        $slow       = array_fill(0, 7, 1.5);
        $slower     = array_fill(0, 5, 2.5);
        $slowest    = array_fill(0, 3, 5);
        $delayTable = array_merge($quicker, $quick, $average, $slow, $slower, $slowest);

        return $delayTable[random_int(0, count($delayTable) - 1)];
    }
