Blur Busters Forums

I don't really understand the deviations too much but the thing that confuses me is that there are holes in my graphs. No deviations but seemingly full dropouts.

Hey blur busters community,
I decided to check mousetester again because my mouse started feeling different and I noticed something I haven't seen before. Maybe someone has an explanation for it? I tried it with several mice and all have the same 'issue'.
