Packaged project's size is larger than what's stated in Readme.md

In my quest to reduce the packaged project size, I stumbled upon this project and followed the instructions outlined in the Readme.md. However, the resulting packaged project size is significantly larger than the reduction claims mentioned. According to the Readme, the project should have reduced the package size to 127MB, but in my case, it sits at 230MB.

I'm using Unreal 5.4.4 and followed the setup steps without deviation. I've set the Binary Configuration to "Shipping", and "Project Settings -> Packaging -> Project -> Building Configuration" to "Shipping". I've also trying ticking the "For Distribution"; didn't change the result at all. Is there anything additional that should be configured or tweaked to achieve the intended size reductions?

Unfortunately, this template is pretty out of date. I last tested it with Unreal Engine 4.26 and 5 Early Access, so the numbers have likely changed quite a bit. I will bring this template up to date soon, when I have some free time.
