Just used the 3x feature for 90 and realised:

It is only useful when you can send your full team, not getting critted and is low on waiting time (this means higher level: in range of 80-110 depending on your deck). I used once and swept 90 effortlessly using the remaining AS:DS from 89.

Solarmist: While your calculations is true, (and you did mention barring crits): use 1 SW for a few team hits will lead to higher chance of getting crit and thus reducing the SW efficiency (of course if you get crit after 3x attack then boo... but the chances are lowered)
