TBH, the majority of those 67 attempts were wave 1 ragequits or w4 ragequits. Both of those waves, while not the most technically difficult plat waves IMO, can absolutely infuriate me for various reasons. And of course there's the usual devices and targets or sometimes just bad object retrievals and shitty escorts.
on that note though I hope these failed sub-20 attempts can help push the Asari Valk up into the top five again in average times per kit:
