Speed Run mod a waste of Time?

Has anyone been getting anything out of this challenge mod? It’s nice that it’s in english now but it feels anticlimactic. We get a chest with a few scrap items in it. Why don’t we get a challengers chest or something worthwhile? It makes more sense to kill the blues and yellows than speed running, also how is the time calculated? Some dungeons it feels like a joke to even get close to the allotted time where others have time to spare.
