You are diving the Optima, thus using HH deco computation.
This might not be applicable any longer since it has been years, but the last stop computation was too short when I crash-tested it years ago.
I reported it to Kevin, but never got any confirmation that it was acknowledge or fixed. So no idea what is the status of the current system.
I doubt that you are "niggled" from a true 10/100 algorithm since (based on what I read from your dive reports that) your max depth is considerably shallower.
Again, other simple factors could come in: PFO, correct ascend rate, hydration, warm retaintion, etc...
Not remaining warm may have had something to do with it initially, but I have since moved to a drysuit. Perhaps the Hammerhead profile is not a true 10/100, I don't know about that though. I have never been niggled until this Rebreather with the HammerHead. I just know that it went away when I adjusted the conservatisim to be less conservative.
