I see the confusion. 100% more of something = 2x more 120% more of something = 2.2x more 120% less of something (problem here!) = 2.2x less = 1 / 2.2 of some

I see the confusion.
100% more of something = 2x more
120% more of something = 2.2x more
120% less of something (problem here!) = 2.2x less = 1 / 2.2 of something = 45% of something
I think the writer meant 2.2x improvement in memory usage rather than 120% less memory usage -- the word "less" used in conjunction with a percentage is confusing.
- dwaltrip 6y agoI think this is how you evaluate X% less: amount * (1 - (x / 100)) So 120% less of 10 rocks is -2 rocks, which obviously doesn’t make sense. Which is good, it shouldn’t make sense to have more than 100% less of something.
