Ok so the reason it was returning wrong values was because I'm just plain stupid.

Basically I do something like:

```rust
WalkDir::new(source).into_iter().map(|item| item.metadata().unwrap().len())

```

Except I was writing this:

```rust
WalkDir::new(source).into_iter().map(|item| source.metadata().unwrap().len())

```

See the little `source` instead of `item` before `.metadata()`? The code compiled correctly but I was getting the size of the source directory, which is by convention a cluster's size 🤦‍♂️

So problem solved, thank you all for helping and sorry for wasting your time 🙏
