The way that I've always seen it is this: you get a random amount of CP, anywhere between, let's say 0 and 6, including all numbers, not just integers. You add .5 to the number for all hours and round according to normal rules. Then, for overtime and double time, you take that and multiply by 1.5 and 2 respectively. Since you may get less than .25 for the first number, you end up with less than 1.5 points as your final before rounding, and thus it rounds down. This may not be correct, but this is how I've always envisioned it.
