I'm a huge fan of TW's friction research. But do take the values with several grains of salt. The CoF value is not the whole story.

Other factors include stiffness, string deformation, and surface integrity over the long haul.

Two crosses with the same CoF: pick the stiffer one in general.

String deformation and surface integrity are related but different.

A slick string can deform or "dent" preventing the mains from sliding. Sometimes these are deep dents, other times there are many little ripples that reduce CoF. You see this mostly with monofilaments such as polys.

The surface of a cross can often fray into a rough texture over time. This too is not captured in the TW data. This is most common with gut and multis and really locks up the stringbed.
