Of course, and 50dB is usually great for intermediates.
But it seems the min values are lower than expected. This is qp 1 intra. You should be getting results higher than prores xq or cineform fs2.
PSNR is good for is detecting lossless (or not), and indicating trends, and potential workflow problems
So I'm wondering if something else going on there
