In this world of multi-use part numbers in the aftermarket, you're not going to be able to nail the OES specs exactly for every single application. You pick a good compromise, test it, and go with it.

If an oil filter is designed to flow and filter well, it will meet the specs of hundreds of applications, that's why one filter can be used on hundreds of different vehicles as seen in the filter application catalogs. Oil filters are not really that "matched" to any particular vehicle.
Think we are essentially saying the same thing.
The most critical thing about designing an oil filter is to ensure the maximum anticipated delta-P is not going to critically effect the engine's oiling system or the filter itself, the bypass valve setting is adequate for the filter's design (ie, delta-P and holding capacity) and the engine application, and that the filter has enough holding capacity to last the recommended filter change interval of the vehicle manufacturer. Making an oil filter to satisfy a vehicle that demands the most in those areas will certainly ensure that filter will be more than adequate for all of the other vehicles they recommend that specific filter for.
