Spin tops are amazing!!!

They are homemade wooden tops one of my teachers used to make to sell us when I was a kid!

Reading the sticky I understood that when it comes to string length, the most important think is where is where the line where the string wound up finishes. My question is should the top fall on the floor perfectly ballenced or as long as it’s falling on its tips the string length is mostly accurate? I am also well aware that my release isn’t probably constant!

Thanks for all the info!
