Yes, the complete list of stages includes 0, 1, 5, 10, 20, 25, 32, 35, 40, 42, 45, 47, 48, 55, 58, 60, 65, 70, 72, 75, 80, 90, 100, 105, 110, 120, 155, 160, 170, as documented here:

I might be barking up the wrong tree, however. If dragons are supposed to start spawning at lairs after Dragon Rising, then things went awry long before A Blade in the Dark.
