Adapting Morten Munchow's standard roast to lower batch sizes

Hi everyone, new owner of an R1 v2 (new to me!) and am trying to learn the roaster. I’ve been watching some of Morten’s videos and was wondering if others had already adapted his 1kg R1 standard roast profile to 350g.

HIs 1kg being: 300C Preheat, Charge P9, D9, F3 → 150C P7 → 190C P5 for a 9 min ish first crack and an AG75 drop at 3 minutes of development.

Would 250C Preheat, Charge P7, D9, F3 → 150C P6 190C P4 get you in the ballpark? Need to order more greens but figured I’d post in case.
