Island Level Requirement Issue: Yes, It's Literally About Cyprus

[Flashlight237]

So yeah, I hopped onto the wiki real quick to see what's up and... Well, here's the deal: https://vsbattles.fandom.com/wiki/Mountain_and_Island_Level_Requirements

While the initial measurements are correct, the way we handle explosion yield messes with the math big time. See, the way the original requirement was calculated is as such...

0.33√(54.265/0.28)/1000=8538.824733 megatons

Divided by 2, we get 4269.412366 megatons.

Yet, the way we have that same formula is written as follows:

Y=(x/0.28)³/1000

Which in the case it'd math out like this:

(54.26494962/0.28)³/1000=7279.207816

Divide that by 2 and you get 3639.603908 megatons of TNT, which should instead set it to 3.64 gigatons (A staggering 18.1% difference).

Even then, I went out of my way to measure Cyprus lengthwise given it's such a long, flat island and got 211.69 km:

Putting the radius instead at 105.845 km. Doing the math there, we get the following:

Y=(105.845/0.28)³/1000=54017.80686 megatons

Which dividing by 2 makes for a yield of 27008.90343 megatons. This would instead set the destruction of Cyprus at 27 gigatons (6.28x the current baseline!)

Going direct off our Explosion Yields page's statement (40-50%), using a median value of 45% drops these further to 3275.64 (3.3 gigatons) to 24308.01 megatons (24.3 gigatons)... And also puts the original baseline at 3842.47 megatons (for a modified original baseline of 3.8 gigatons).

So uhh... How are you guys gonna handle Cyprus, hmm? I'm not asking for any changes; I'm just asking why the math here is so wonky.

Come to think of it, why did we decide to use Cyprus as the standard for all of this?

Probably some old thing. Personally, I would've gone with a similarly sized yet less oblong island, like Viti Levu from Fiji: https://en.wikipedia.org/wiki/Viti_Levu

Or Buru from Indonesia: https://en.wikipedia.org/wiki/Buru

Heck, Viti Levu would actually let this site KEEP the value at 4.3 gigatons but instead have it based directly on the formula from the Explosion Yields page instead of older math. My math for it comes down to this:

√(10388/π)=57.50307033=~57.5

(57.5/0.28)³=8660230.275 kilotons

8660230.275/2=4330115.138 kilotons=4.33 gigatons (4.3 gigatons based on how the Wiki puts things).

Me personally I think we should use the actual diameter of said islands instead of finding radius from their areas, as these islands are small enough to allow using their longest sides for our explosive diameters.

In that case, the island most closely matching our baseline, though still a little too far to be the matter of a simple justification change, would be Lombok in Indonesia, going for 110.27 kilometers from end to end on its longest diagonal:

Even then, we are getting a radius of 55.135, which using our current understanding of the explosion formula leads to this:

(55.135/0.28)³=7634982.443 kilotons

7634982.443/2=3817491.221 kilotons=3.82 gigatons

Yet going off the median of 45%, it's more like 3435742.099 kilotons (3.44 gigatons)
