I'm now noting that my nodes running core V 20.2 now shows over 1 gigabyte in each of their local mempools while mempool dot space shows 1.74 Gigs.  That should mean I'm seeing the majority of the mempool dot spaces mempool however this should not be possible as also according to mempool dot space more than 50% of the current mempool is taproot transactions, none of which can be seen by my nodes.  Something seems amiss here. It should also be noted that among my nodes the discrepancy in memory usage and TX count continues amongst them unabated since Taproot's introduction.
