You need to increase the sample value.
Using the two values version may help.
Have the pretrace go deeper.
As for the count, use the two values version for nearest_count.
Try this version :
pretrace_end 0.0025 // or even 0.00125
// more pretrace sampling almost always reduce noise and artefacts.
count 350 999 // Should reduce those dark splotches.
// Second value set a sampling direction pool.
// Second value MUST be greater than the first
recursion_limit 2 // 1 may even be enough.
nearest_count 20 5 // enable adaptive sampling and pretrace
// second value must be the smaller one.
// Larger first value often help to reduce the dark splotches,
// and also make then less sharp.
Try raising the oscilloscope a little bit above the table. After all,
most have rubber pads under them acting as short legs.
