I’m getting 1 dive between failures (4 failures so far) and am pretty sick of it. Any ideas what could be causing a persistent 1st stage o-ring failure? This started after the reg was serviced. Was something missed?

That's what i told him in the other thread. Low duro oring. Apparently he wants a different answer?My first thought was an incorrect Duro o-ring (70 vs 90) with it then extruding shortly afterwards.
Do you have a pic of one of the failed o-rings you could upload?
Failure modes usually have fairly distinctive features...
However if both shops are using the correct OEM Atomic service kit it is more likely to be physical damage to either the Yoke Retainer sealing surface (dropped?) or the inner sealing surface of the Body (scored by a careless tech?)
This is probably the right answer. It's best if the technician holds the yoke nut upside down, pointing the O-Ring towards the sky when assembling. Twisting the yoke nut and having the O-Ring point towards the floor can make it fall out of place during assembly.You need to be careful that the o-ring doesn’t fall out of place when assembling.
