Is there any reason why git-lfs might push more than the files size to github.com?

Question

I wanted to get started working with git-lfs to push a 800+ MB binary to github.com for distribution. I'm seeing

> git push origin installer
Git LFS: (0 of 1 files) 65.72 MB / 860.12           Connection to github.com closed by remote host.
Git LFS: (0 of 1 files) 1.03 GB / 860.12 MB

after

git lfs install
git lfs track [file]
git add [file]
git commit -m "[message]
git push origin [branch]

Is there any change that exceeding the size of the file is the expected behaviour/not a bug?

I'm considering splitting the binary into modules and keeping it below 100 MB, but the issue still makes me curious.

I'm aware of how to work with large files on github.com.

I'm using git-lfs 1.5.3 on Ubuntu 16.10 and public github.com repositories.

Progress meter duplicates bytes sent after retries. There's an open issue in Github :
