Maybe they meant 50%-200% slower, in which case the x-factor range would really be 1.5x to 3x?

- hinkley 3y ago200% slower is 3x as long, yes.
- dr_dshiv 3y agoI love making fun of people that don’t understand percentages… wait, wat?
- hinkley 3y agoWho is the intended butt of your joke here? And explain to me why it isn't you?
- CookieCrisp 3y agoI am pretty sure they intended the butt of the joke to be intentionally themselves
- jychang 3y agoHe’s being self deprecating, yes
- froggit 3y ago117. 472% of grade school students are unable to readily convert between fractions and percentages. 38.157% of informally provided statistics are made up on the spot under the assumption nobody will actually check.
- danbruc 3y agoBut 50 % slower is either 1.5 or twice as long, depending on whether the 50 % refer to an increase of the runtime or a decrease of throughput. 200 % slower is only unambiguous because the throughput can not decrease by more than 100 %.
- hinkley 3y agoUsually that’s “half as fast”. English has always had the terrible twos. Is biweekly twice a week or every two weeks. I’ve been doing capacity planning lately and the whole deal with how we are bad at fractions came up again. If you have to spool up 10% more servers and then cut costs by 10%, you’re still slightly ahead. If you cut 10% and then later another 10% you have cut 19% of the original, not 20%.
- mrighele 3y agoI think it still wrong, although one may understand what the other person means. When we say "faster" or "slower" what we usually mean is that we add/remove the percentage to the original amount, which is often cause of misunderstanding. "Y is 10% faster than X" means that Y goes at 110% the speed of X "Y is 10% slower than X" means that Y goes at 90% the speed of X In particular, "Y is N% slower than X" doesn't mean that "X is %N faster than Y" ! (110% of 90% is not 100%) For example "Y is 100% slower than X" doesn't mean that "X is double as fast as Y", but that Y is not moving at all. and "Y is 200% slower than X" means... that Y goes in the other direction ? (Maybe back in time, in this case ?)
