TTA results Higher when using a 33/67 mix of 2TTA and 7TTA instead of 7TTA

[nonogamester]

after lots of experiments a upscale image with esrgan with 33/67 mix of using a overlay of 2 levels of tta and 7 levels of tta level is better than either seperate.( levels of tta being how the 7 different directions a image can be rotated/mirrored without resizeing the canvas the results overlayed for a higher psnr) my vague thought of why the mix of 2tta and 7 tta is better than either normal implemation is that 2tta is most well rounded but having a 33 percent mix of the 7tta gives extra info boost to accuracy. other ideas why this is Welcome ‽
