That's completely germane, but he didn't say 100% faster, it's me that said twice as fast.
I posted a quote. "Others say it’s closer to 100%.". As Igor said, it's illiterate nonsense. I posted a jokey reply.
Speed is measurable say as number of operations per second (ops), if my
score is 10 ops, then a 100% increase of speed => 20 ops. I love percents, for you can say one thing, and be sure another will be understood ;)
That's why one must use a well-defined unambiguous measure of performance: new - old / old, hence 100% faster is at best ambiguous and at worse meaningless.

Same argument. What does it mean to complete a task 100% faster? What does it mean to reach your destination 100% faster?

I would interpret twice as fast, and that's only 50% rather than 100% reduction of execution time :)
relative performance = new time - old time / old time. 2x = -50% 3x = -75% etc
-100% means new time = 0, and performance is infinite.

"The benefits? Some sources are reporting a 50% increase in speed. Others say it’s closer to 100%. Many claim they’ve seen their battery life increase by 25% or more!"
Got to love those 100% speed increases. Apps really fly when they take no time at all...
