between deflagration and explosive? Is there a jump or is it a
continuous ramp up depending on source? Or is this just experts
letting us in on the details or something practical we can use for
pyro staging?<br>

<div>Technically, gunpowder in confinement still doesn't explode.
The term is "deflagration," which is also what fuel vapor does
in your engine cylinders. It's still burning, however the flame
front is moving *EXTREMELY* rapidly... Much faster than "normal"
unconfined burning, but much slower than an actual explosive
event.</div>
