I have spoken to the calc group about this and they either find the idea that we only consider an explosion an
Air-Burst because of a Mach Stem to be absurd. Or they have
never heard of anything like an Air-Burst only being considered for the formula if it reflects off the ground.
As I've repeatedly explained myself, something as important as this would've been mentioned on our page. Not only that but the page you're linking to at no point says that the air-burst formula can only be applied when an explosion has a Mach Stem. It's just explaining what a Mach Stem is and how it can affect air-bursts.
Doesn't say anything about how not having this happen disqualifies it from being an Air-Burst.
Ignoring the fact the explosion would reflect off the ground and back at the explosion anyone, since it doesn't matter which way you measured it. It's a omni-directional explosion and goes in every direction, not just the way you measured.
CloverDragon disagreed with you about the explosion reflection, Damage agrees with me that not using the Air-Burst formula for this explosion is wrong, and the calc group members I've spoken with about this topic agree with me as well. It's clear to me you just need to use the air-burst formula as this is a mid-air explosion.
At this point if you still actually disagree, you need to make a calc group thread. As I've shown, none of the calc group members I've spoken to have ever heard of a Mach Stem being needed to qualify for the air-burst formula nor do they understand why this would be the case.
