After getting a pmkid file from a capture with -k, should I depure It and erase repeated ESSIDs ?
Yes you can do it, if ESSID and MAC_AP is the same - that will speed up hashcat a little bit
Do you apply rules or masks with the ESSIDS list after -E
No, i only use hcxwltool on them
Would it make sense to combine all the output from -E from all the pcapng ?
Of cource yes - that will update your database/environment.
Also cat all .16800 to an archiv.16800 and all .2500 to an archiv.2500
Than, from time to time, run your -E archiv against them.
