Fated End vs 50% Alt Qual Doom and Cursed Ground

I've been testing how Fated End compared to the other two and I feel like even if you hit the effectiveness or overcap it, Fated End feels like a few frame slower compared to the other two or maybe it's just my testing.



How this theory "tech" works, curses has already 100% base effect and you only need to get more effects on the tree and other item to instantly trigger doom blast using only this ring in theory(?), it's working for me but not 100% sure.

If anyone can also test this, it would be helpful. If it is a few frames slower, for anyone who's a pro at this, would that few frames be detrimental to spamming doom blast?
