Generally speaking in dailys you want -atk to do your sureshots, the chance for a random low attack win increases as the attack increases, so compare 80 attack versus 100 attack and 40 vs 60, the 80 will win over the 100 more times. Also, 20 vs 40 is a sureshot, but 40 vs 60 isnt, so you want to keep everything low. In ELO, that doesnt matter, theres no random, and you dont want to sureshot (means you've overpilled), so absolute values are more important, its why rescue, with +12 is so favored, its always 12, compare to montana's min 8, which is a rather high minimum, which is why uppers will see play alot.
