Comparison of yolov5 and yolov9-gelan results

[gpsamt]

I am comparing the results of the Yolov model in a dataset with 4 classes. Between yolov5, v7, v8 and v9. I got results of 98.4 % precision on yolov5n and v9-gelan. Higher value than versions 7 and 8. How can this happen in the case of version 5?

yolo series are not released by the same author, hard to say which one is better, I believe yolov6-3.0 is better than v5, v7, v8.
