First, how do you know it didn't use oil during the ff period? Could've used and diluted then as well. Four or five ounces of oil consumption during an OCI is hardly unusual for any engine, new or used.
Second, Honda dipsticks are among the worst, so getting a reading accurate within a few ounces is no easy task.
Agree this is all supposition, but you won't find a more accurate fuel dilution calculation than you'll get from Oil Analyzers. Either their method is wrong or it's hard to get a consistent crankcase level reading. Or maybe a little of both.
