Well the thing is, we know the size of the explosion but we don't know the rate. Deidara refers to them as C1 and so on, but for all we know the rate of explosion might have been slower than gunpowder in the Naruto universe.

Other Shinobi have had virtually no time to do things too, and only were that fast to have a cool frame of them appearing out of nowhere. Naruto blitzing Kaguya from such a far distance when Sasuke couldn't with teleportation, the weapons Pain jumping in to protect the Deva Path before Kakashi could notice with his "eye that takes in every detail." Some things just happen so the story progresses in a "cool" or "impressive" way.
