Instead of reducing max_trace_level, it's often better to increase
adc_bailout.
When max_trace_level is reached, black is returned.
When the tracing stop due to adc_bailour, you get the current
evaluation, not black.
In your case, you probably won't see a speed degradation using a larger
max_trace_level. No change expected going from a value of 4 to to 50 or
more, as sdc_bailout would kick in pretty early.
The default adc_bailout is 1/256. Your 0.01, or 1/100, is better for
your situation. You may even use something like
adc_bailout 0.03
Without issue. It may make your rendering go a little bit faster.
I very often increase adc_bailout for test renders.
