One comment I would add, is that you should enable a Client Setting if you wish for the client to continue evaluated older superseded content. See the thread at Supersedence handling change for Windows Patches
Otherwise, last month’s rollup packages will appear to be remediated even if the patches are not installed, due to the way a client will mark the update as non-relevant when the fixlet is marked as superseded.
Without evaluating superseded content, you cannot determine how far back the client is unpatched, only that it is missing the latest month’s (non-superseded) content.
