PicoFly installation - Divisions by zero

[https://lemmy.dbzer0.com/pictrs/image/e0a00132-2018-449a-928a-80605a45cbf6.webp] I’m working on my first PicoFly installation. The guide I’m following suggests to solder the points on the cable first rather than after putting it in, which is what I’m currently working on. Does it look OK or should I add more solder before proceeding?
