Are the 3 demons glitched

I have 236% str and over 600 atk.... without demons range is 188k clean, with 1 demon it goes to 189k, 2 demons it goes to 191k and 3 demons it goes to 193606. Still doesn't seem right because even getting 1 more on my noble mind on my cygnus adds like 1.3k to my range and that 4 atk from jett added almost 3k

That's actually impossible because to have a 3k increase from 4 atk at 188k range, you would need to have less than 250 attack. Your anecdotes aren't even consistent with each other. 1 atk gives 1.3k. 4 atk gives less than 4x1 atk. Good try at being math though.
