Alan T:
Very little, I'd say, as it was very close to a tif version
of the original, at a pixel level. Saving jpegs as jpegs
after reworking several times is probably a bad idea, though
I've got away with it quite often.
Why not try it and see? You'll see differences and jpeg
artefacts quite easily at high magnifications in an image
editor.

Alan T:
27-40MB tiff from Scanwit/Vuescan at 2700 ppi.
