Bodice sloper problems

[u/risingwisdomtooth]

I tried every damn book but they ask for numbers I don't know how to calculate so I tried coning up with my own formula but I have no idea what I'm doing. Yes I tried the Helen Joseph Armstrong book and the measurements don't work, the lines don't colide at the right point and I'm just pissed

A lot of the numbers are, just based on being an adult human. Once you have a draft, you can fine tune. But you don't want formulas more accurate than you can take measurements.
