I'm storing the powers, not the values. So, the powers are 10, 20, and 30. I then take it to the power later. Thus, it's not buggy (at least from an analysis point of view).

I was suggesting another solution. In no way do I ever say that you have to do it this way or I'll come over to your house with Vino and Guido to break your kneecaps. :-) And, in fact, you're right about calculating the values ahead of time, but not for the reason you think. The best reason is if the requirements change and there's a new block size called HH that resolves to 734623 bytes. My way is a little obfuscated. Your way is more explicit. Good call!
