Having used a variety of pads, made of a variety of compositions, my (limited) experience matches some of their findings.
There is plenty of application-specific information & tips, such as:

Some organizations run a format of one warm-up lap, followed immediately by a very limited number of hot/timed laps (one to three), culminating with a cool-down. Just as with autocross, a brake pad that doesn't need a substantial amount of heat to provide stable maximum friction can provide a great advantage. In this regard, a sintered pad has the advantage over other pad types.
