Just wondering, why do we want do exclude PSL matches?

[engedy, 2017/05/22 10:32:28]

PSL matches will be included inherently in the other histogram I'm planning to
add (about same site-name matches), so I thought that I'd exclude them here to
make the histograms disjoint, but I don't feel strongly about this and happy to
include them here as well.

[dvadym, 2017/05/22 12:42:25]

Acknowledged, I'm ok with separate histograms.
