Well, if you were smart, knew some physics and math, you'd know by yourself how those calculations work, and you'd understand. Math is not my subjective opinion.
Again, yes, what I showed is that something like that wouldn't scorch grass. The blast is way to short to heat up its surroundings. If it lasted a couple seconds, sure, it'd burn the hell out of the grass. But at 0.16 seconds, it just doesn't deliver enough heat. This is, essentially, what I precisely calculated, and you'd already know this if you hadn't slept in school during math classes.
