Since you don't have that engine, I'd listen to the OLM rather than go on time or mileage, neither of which are going to be as representative of the oil's condition.
If you want to change it early, I'd go on a % of the OLM, say 20% or so, but it's really not necessary. Given the length of the OCI though, I'd make sure to consistently check the oil level (that's a good idea anyway).
Some people would rather be safe than sorry. Engine repairs cost a lot of money, how much does an extra 5-10 oil changes cost over the life of a vehicle? I bet it's a lot less than a tear down and clean up, or a rebuild of an engine. Blind faith IMO is not good, nor is dumb luck. If you plan on following the OLM at least obtain some data to back up that the oil is holding up, and you're not harming the engine.
As far as the Honda OLM working well in all of its engines except one, I'd rather not find out I was the guy who owned that one engine the OLM didn't work for. Or an owner of a GM DI engine that had to have the OLM reprogrammed because the OCI was too long. Sorry I respectfully disagree, especially when it might only cost me another $200-$300 extra {if that] over the life of the vehicle to change the oil a little sooner. Opinions vary.
