Feedback on Pfitz 12/55 template

Hey y'all,

I'm running the Stockholm Marathon on 30th of May and look for feedback for this ChatGPT generated 12/55 Pfitzinger trainings plan. My goal is to run 3:15, and I'm currently on 60km a week with a 10k in 43mins and 1:34 roughly for a half marathon, so I've got some work ahead to achieve the time.

Since I couldn't find any specific info on the 12/55, I took inspiration from the 18/55 posted here... https://www.reddit.com/r/AdvancedRunning/comments/azrpy9/pfitz_1855_marathon_template/?share_id=7RRoeEdNeI_pwjgJ7r5Ef&utm_content=1&utm_medium=ios_app&utm_name=ioscss&utm_source=share&utm_term=1

..and created a template you can access here: https://docs.google.com/spreadsheets/d/1A0IMg2hGO6ULBL8ani1rk-wul1_9gH3cId7cCuSqulE/edit?gid=1494545752#gid=1494545752

Curious to hear your feedback since it seems a bit too repetitive for me.

Thanks!!
