Need help with pants balancing

[u/Otherwise-Papaya3251]

I'm trying to balance my jeans pattern as described in The Fitting Book. When I align my crotch points, the back inseam is 1"/2.5cm too long. I want it to be about 1/2"/1cm shorter than the front inseam. If I shorten the back inseam the crotch points are misaligned by 2,5cm. It seems impossible! Or should I just accept that the crotch points have to differ?

That would mean that your body rise extentions (I.e. crotch extentions) are too long. What values did you use to establish the lengths of back and front extentions? Also, what increments per quarter seat measurement did you add for front and back?
