A Great Old-Timey Game-Programming Hack

Your only "mistake" was to switch to a different measure when giving the percentages. Your calculations are actually fine, because you explicitly label them "speedup".

However, this can confuse a non-thorough reader because your previous measures are not about "speed"; they are about "cost" (cycles). The parent just did not realize the switch, and thought that you were claiming to have reduced "cost" (cycles) by 30%/70%, which wouldn't be true.

Thanks for this insight! I never would have seen it had you not told me. (I'm an engineering guy and switching between time-per-unit and units-per-time is so automatic for me that I didn't realize it wasn't automatic for everybody.)

I've updated the story to explain the calculation the first time it happens.

Thanks again!
