All depends on the tune of the engine honestly.

The R18 engine found in the 8th gen Civic and HRV can go 500k without needing any adjustment, yet the K-series engine in Accords/CRV's have SUPER tight exhaust valves causing the engine to misfire even after ~60-70k miles.

The AP1 and non-DBW AP2 almost never need adjusting, same cannot be said for the DBW AP2 as we know.
