[cyberpunk 2077 edgerunners] How does a spine implant added to organic body allow user to not only react but also move 100 times faster?

David in organic form with sandevistan does not just have crazy reflexes but is also incredibly fast, bullet dodging fast (which are faster than sound, unless in 2077 for some reason all bullets are subsonic). 
While it's been hypothesized that part of human reflexes calculations must take place in the spine becauase they are faster than electric impulses cpuld possiblt go to brain and back (such as stopping hand once object is reached), for this kind of stuff you still need the brain to decide where to go. 
But let's be generous and say that the sandevistan is not just a spine implant but also a brain implant.  
How does a spine and brain implant that can boost reflexes make your organic legs move faster than bullets, and protect your body from G forces?

Removes the latency from organic signal broadcasting. Instead of a say .003 reaction time for a signal to go from your brain to your finger it just directly transfers the signal at .001 instead. It doesn't do anything for enhancing your body's natural resistance to the acceleration and such but if you're already using chrome instead of meat it's nothing to be worried about. But the enhancement on an otherwise organic body is limited and dangerous. While the Sandy has a large mount along the spine it's actually thousands to millions of nerve endings that snake throughout the body replacing most of a person's major nervous system with a cybernetic one.
