My point is they should cave to their own voice.

If they advertise by direct statement or implication that this is a sim generally based upon real MLB, it should be generally based upon real MLB. (And that should be what they advertise and do, since that is what we want to do -- that's why people do HBD.)
That "true north" may need a bit of adjustment from time to time, but makes any adjustment true to life, minimal, and even predictable.
It also will please customers the most, over the long run.
