percentage ackerman

I know. A can of worms, but bear with me please.

My project uses mini front hubs. If I use the mini steering arms swapped over from left to right and pointing forwards, not back, it gives me 15% ackerman steering angles, that is 15% of the way from no ackerman to full ackerman.

If I made my own arms, or had them made, I could fit in upto 66% ackerman.

Is 15% enough? what are the good and bad points of having less than full ackerman angle.

BTW, my project is a lightweight trike with the single wheel at the back.

To gain quasi-ackerman move the steering rack further aft.

With a trike how much ackerman to use is beyond our Ken & Barbie but I reckon it ain't going to understeer at turn in and at the cornering limit the inside front wheel will lift.
