> Where to allocate is one question. Independently, this comment describes the size of the cells in the class. That size is 128, not 128 - preciseStep.

Are you sure? The comment said:

// [ 128, 256... 1024 )

The size of the first block is really 128, but the second is 128 as well, not 256, and the last is 128 as well, not 1024. Instead I think the comment describes the ranges, the first range is [128-256), the second is [256-384) ...

The growth rate is clearly linear:

static const size_t preciseCutoff = 128;
static const size_t impreciseStep = preciseCutoff;
return m_impreciseSizeClasses[(bytes - 1) / impreciseStep];
