Remember Stan we are speaking of detonating cord here not propellant powder. My understanding is the detonating cord does not burn as such, but travels via a shock wave. Once set off it is essentially All At Once. I do not believe a time nterval could even be determined for it.
Dynamite has also been set off by low voltage electric current by magneto boxes. You know the type with a T-handle plunger on top as seen in the movie "The Bridge Over the River Kwai". I have one of these boxes & a big role of wire, but no
"Dyn-O-Mite".
