If you get wierd reading with LightSpace and PGenerator, it may be wise to check you cat5 ethernet cables at first.
I had defective one from PC to router and after replaced it with new one everything works like dream.
Using RPi PGen again via ethernet.
At one 1000p verification got two meter errors but every other measurements went just fine.
At today got three bad measures with 9261p profiling
If I understood correctly what Ted wrote, with ColourSpace it´s possible to remove bad readings.
At next time I use 0.75 extra delay instead of 0.5.
