I'm not that sure of your interpretation of this timming.
NAV ADR DISAGREE was time-stamped at 0212 during the ACARS sequence. As I understand it, this is a cockpit effect (WRN) and not a fault (FLR), then, I do not think that it needed a correlation window to open before being displayed and an ACARS triggered.
Consequently, as it takes 5-6 seconds for ACARS protocole and 10 seconds to trigger, I would rather time it at 0212:51 less 15-16 seconds -> 0212:35.
Everybody seems to interpret ADR DISAGREE solely in relation with airspeed issues. So far, I don't know if it was only airspeed related as both AOA or pitot probes measuring values outside of their valid envelope could have basically the same effect.
