I rather actually see a real comment if there is no time to create a unit test.
Why does changing ZQ_PEDERSEN to ZQ_WILLIAMSON fix the bug?
Having meaningful named constants would make much more sense.
Edit: On full view of the code, the bug could be avoid if they broke out the if <demoninationX> blocks into their own function, and to prevent "typo" errors, it would be good to have a local variable named current_demoniation = demoniationX, and then reference that local variable instead of referencing the constant everytime.
