Of course this table didn't render correctly. Here's a readable version:
| Repo     | Standard Repack | With --full-name-hash |
|----------|-----------------|-----------------------|
| fluentui |         438 MB  |               168 MB  |
| Repo B   |       6,255 MB  |               829 MB  |
| Repo C   |      37,737 MB  |             7,125 MB  |
| Repo D   |     130,049 MB  |             6,190 MB  |

Thanks, -Stolee
