Since it's your intention to keep the digital ECM updated I'd like to point out that a correction I submitted to Klaus Wachtel in 2018 does not seem to have made it there. All the twelve minuscules listed for reading a περιελοντες in fact read b περιελθοντες, as can easily be verified.
Also, GA206, listed in the zz line also reads b περιελθοντες.
Thanks.
