K-1 has been speeding up drastically compared to the stats you are referencing. Has CR-1 done the same in 2023?
Based on current processing trends in 2023, someone filling an I-129F in May will have their NOA2 by Feb 2024 and their embassy interview sometime in summer 2024 (country dependent), so you are looking at ~350 days now until interview for K-1 vs CR-1. Unless you have proof of drastically reducing CR-1 processing timelines in 2023, the days of the K-1 being faster are back.
