Rank reduced from 128 using "LoraReduceRank" -node in KJNodes, which is basically kohya's script: https://github.com/kohya-ss/sd-scripts/blob/main/networks/resize_lora.py
Quick comparison (note that this isn't accurate test of the reward lora itself, just to compare the effect of reducing the rank)
