Howard, this is 100% on-point. around -15-20, depending on servo throw will actually make up for mechanical positive expo for linear steering. I go for around -30 for a easy to drive, less twitchy car with the sharp turn-in when you need it.
Buddies who have driven my cars always comment it is easy to drive and "dialed" - sometimes i can't even drive theirs it is so twitchy / sensitive.
