What is "cutting by 40x" supposed to mean?

Cutting latencies by 40x! Unfortunately couldn't fit the whole title in the character limit :<

How can you cut latency by more than 1x? I am no intending to be snarky, it just doesn’t fit my brain how you can reduce a measure time by more than the original starting time.

There are two ways to express such ratios, and both are equally valid. (Though "x" is usually reserved for "40x" and "%" for "97.5%".)

Put differently, 1/40 is not the same as 1x - 40x. I’d phrase as Reduced by 97.5% or 0.975x

probably just AI slop and using wrong semantics, they mean speedup ratio.

You're absolutely right!
