They aren't.

The question, perhaps, is why are your granted points always less than you claimed points? This is nothing to worry about. It just means your computer claims slightly high for the work it does, and when credit is normalised, you end up with less than your original claim.

Some other people will always claim a little low, and always get more than their claim. But equal points are granted for equal work, no matter how long it took you, or what computer you used. That's the aim, anyway.

Thanks for the response.

How do you control the "claimed" for my computer?

I suspected that the system used would be complicated. Thank you for taking the time to answer a trivial question.
