Please don't say all of them.
I feel like that is the answer though lol. What does everyone find acceptable or what does everybody shoot for. I'm guessing there's no magic number.. But if you shot 100 A's would you be ok with 20 C's? 10? None?
Is it skill level dependent? Obviously I try for all A's but that doesn't happen. Is all A's unrealistic while still being fast unless your super squad? Is there anyway to find out what the super squads are shooting?
