@RueNahcMohr no no, looking at the schematic, there's:

GND <- LED <- probeA <- CAP <- probe B

you said:
green is probe A
white is probe B

so purple is B - A
a.k.a. white - green

but if you look at the graphs:

white spikes
purple: saw
green: spikes on top of saw

so it'd appear that green = purple + white, IOW:

purple = green - white

something's backwards
