IMHO, when I click "optimal size" it recommends a size where each source pixel maps to at least one remapped pixel. Bluntly said: If I take three portrait 2500x4000 images and align them next to each other, my "optimal size" will have a height of 4000 pixels (plus whatever is needed because they don't align perfectly). In this situation, I have the impression I can clearly see that the remapped images are softer, fuzzier than the originals.
