Thanks for the new BCheck and also improving the others!

The new one looks very interesting, but I wonder if it would be better as a per host check (given host) rather than a per request check? Currently this will issue a request to /run per audit item.

Thanks for your correction, it would be better to send requests to each host

[QdghJ]

Modified to send one request per host
