Will USCG accept we conducted on going training and practice on a sea service letter

Hello in the past when I renewed my license I would always include that we conducted on going safety training and drills on a regular basis . The USCG was kind enough to accept it so I did not have to do my STCW ( I am 62 with a 500 master.) . Most of the time I submitted this was on inspected vessels. This time its all on 1 yacht as a mate. question is will uscg accept this for a yacht. . I do realize after this year renewals will have to do it.
