Using default checkpoints. PSNR/SSIM usually improve until the 4-th step.
Is it normal that images only deteriorate subjectively after the 1-st iteration and never improve?

Examples:
img_002_SRF_2_HR_1
img_002_SRF_2_HR_2
img_002_SRF_2_HR_3
img_002_SRF_2_HR_4
img_002_SRF_2_HR_5
img_002_SRF_2_HR_6
img_002_SRF_2_HR_7
