The warning message should work fine now. Testing it is not intuitive, because you have to limit the download speed manually. Instead you can set the warning limit higher to something like 12 MB/s in open_mastr/xml_download/utils_download_bulk.py:58 and run the following script:

from open_mastr.xml_download.utils_download_bulk import download_xml_Mastr
import os

# xml download
save_path = os.path.join(
            os.path.expanduser("~"), ".open-MaStR", "data", "Gesamtexport_test"
        )
download_xml_Mastr(save_path=save_path)

Only a small spelling mistake.

Looks good.
