How is what I said not true?
A smaller bioload in a tank will allow ammonia to accumulate more slowly.
In a 20 gallon with 24 neons (overstocked, imo), the fish will put out enough ammonia that if something in the tank causes the cycle to fail, or something happens that causes half the fish to die, there will be a large spike of ammonia. If the cycle is still intact, then it will still take some time to get rid of the spike created, risking the lives of the fish in the process.
In a 20 gallon with 12 neons (just right), the fish will still put out a sizeable amount of ammonia. However, if will be half of what the 24 neons would put out (I'm aware that it's not exactly half, but it's a decent estimate) which means that in the case of a cycle failing or a large amount of deaths, there will be less ammonia in the same space.
Stocking lightly does create more stable tanks.
