If what everyone here say is true, "Lua Programming Gems" is wrong
(unless it is trying to *redefine* the meaning of % faster)
Quote from chapter 2, Lua Performance tips :
https://www.lua.org/gems/sample.pdf
When I say that a program is "X% times faster" than another it means
that it runs in % less time. (A program 100% faster would take no time
to run). When I say that a program is "X% times slower" than another
I mean that the other is % faster. (A program 50% slower means that
it takes twice the time).

I ALWAYS use speed ratio, say 1.143X, to avoid this ambiguity
