I've had a bad run or two, i broke an over 80% cobalt winglet on double down and an over 70% on double down, etc etc
Regardless of what the chance of failing high % things repetitively is.... its like playing roulette, you bet on black, it was red... this happens five times in a row..... so now black is "DUE"! its still just 50/50 though.
It sucks that you feel victim to that ~20% or whatever each time, but its still a 20% chance to get nq regarless of how many times in a row it happens lol.
