How long are are the bungee cables?

Hi all, I’m excited to get my Maslow up and running with the Default frame but I’ve run into an issue.

The instructions don’t say anything about how tight the bungee cord is supposed to be.
Out of the box it’s far too long (shown in my picuture). I cut one about 32" long and it snapped before reaching the end of it’s range of motion.

Before I break anymore cords…
About how long should the bungee cord be?

replace them with weights, they work much better
