Changing the pretrace_start usualy have little to no effect. Keep the default of 
0.08.
Changing by some small value may, in some cases, get rid of some artefacts near 
corners.

Default value.
Try reducint this to 0.01, 0.005 or 0.0025

Maybe a larger value here? Try 600 or 800.

That's the default value.
You can go up to 20. Low effect on render time, can greatly improve end result.

Default value.

Meybe try a somewhat smaller value. Will take more time on the final pretrace step.

Default value.

Default value.
You may need a value larger OR smaler. Don't go over 0.02. Don't go to small, as 
smaller values will increase the render time.

Default value.

That's 0.025, probably to large. Try adc_bailout 0.01/3 or 0.01/4.

Default value.

Every time you use a default value, you can skip that option.
