Magnified effect and skill AOE radius, whats the math?

If I put Mag Effect for the 40% more AOE onto herald of ash, it goes from 1m radius to 1.1.

Base area is 3.14m^2 (A=πr2=π·12≈3.14159), 1.4* that area is ~4.396m^2, I get ~1.18m of radius. Am I losing the .08m to rounding? Or is the skill sheet just chopping off the second digit?

I really dislike that this is still a thing in PoE2 .. and it feels worse than in PoE1.

When you see a 40% modifier .. it really should be 40% of something tangible to see, not 10% of something you can see because "Tenichally!" it's increasing by 40% but that's all spread out along the whole area. It's absolutely not intuitive, and anything that forces players to look into the deep nooks of the game online or trial and error is a bad implementation.

It really should go back to diameter, just like how melee is based on distance; that way it's easier to visualize and conceptualize at a base level, without having to do any wonky halving when you test it in game by casting spells next to each other to count.

Then you make the increases shown on passives / gems / etc. show as the % increase to the diameter .. which functions just like melee range increases. That makes it super intuitive, since a 30% is way easier to visualize when you're measuring on the ground and see two axis of it grow by 30%. It also means when you look at the tooltip, and you see "1.0" it doesn't move to "1.08" and confuse the heck out of you, thinking something is very wrong / a bug. You'll instead see the "1.0" go to "1.3" and all will be well.

And for that matter, why don't ranged skills show their travel distance?!
That's SUPER important! SO many questions could be answered by just being able to tell that projectile speed did something tangible in on the screen, or being able to figure out at a glance how skills match up with each other without having to go through tons of arduous testing in game spamming skills to do it.

As it is now, I have no real clue if anything works right in PoE2, because the numbers don't match up with each other, and visually on the screen it could be really misleading because of terrain, lack of marker consistency to test with, monitor size differences, etc.. Seeing a "1.6" go to "1.7" just makes my heart sink with a large 40% modifier. Don't even get me started on the one that puts on a long cooldown with it ... just seems crazy to use it.

If it's anything like boss hitboxes it could be any size, nobody knows, random maybe. Might even get smaller.
