Great  I’m glad things are improving for you.
About the object score - In the official Yolov3 repo, the author used an object score threshold of ~0.25 to decide if the bounding box should be considered. YOLO in nature are biased in creating low object scores thanks to 99% of predicted boxes aren’t matched with a ground truth box. So I’d advise you to not try to increase the object score but rather find the sweet-spot for the threshold. Maybe I’m missing something in why you’d like to increase the object score so feel free to explain
