Alex, when I add shims to the steering knuckle it seems that I get a bit more steering. When I look at the car on the bench it looks as if I should get less steering mid corner. I notice you use shims for bump steer in your set-up. Could you please explain ?
Thanks.

More shims under the steering knuckle will give you more mid corner steering, most noticeable on asphalt and bumpy tracks.

Alex, does more or less bump steer also change ackerman?...and if so, is it the same or different than changing it inboard the standard way? Also, I know when running front toe out that reducing the static toe out can also increase mid-corner steering as this changes dynamic ackerman.. is there a preferred way or method to determining one adjustment over another? Are they finer increments per se' of the same adjustment? If you could kindly elaborate , I'd greatly appreciate... Thanks.

You are right, when you change the toe, the ackerman is affected as well. If I remember correctly, the bumpsteer should have no influence in the ackerman setting.
