Do you know a better way to force Calibre to update the file size?

Manually doing this, my suggestion would be to open the containing folder for the book and copy the book to another location. Then use the remove books of a specific format to delete the book which leaves the information and then dropping the book back on the details pane.
Though looking at one of your later posts, I have trouble believing in reducing the size of an epub from 150MB to 10MB without turning the embedded images into crap. The only permitted compression methods in an epub are uncompressed and Deflate-compressed. Recompressing a 200+MB book (
The Prophets of Smoked Meat by Daniel Vaughn) which was mostly images using the slowest Ultra option for Deflate compression took the file from 203MB (212,980,057 bytes) to 202 MB (212,616,217 bytes). Doing a lossless recompression of the images saved 26MB (399 image files) of of the original 207MB.
