Know - no. But drawn from my experience, such figures vary widely with Hardware and Software. I'd also suspect modern chips may not be optimized for a mode which the average machine runs ca. 0.2 sec/boot (before switching to some super-important branding screen). It's not considered worth the extra effort to make it work well, instead of just work.
