This contest is easy, if you have been paying attention, and spending your resources wisely.
I'm ~2m shy of 6th progress level, and haven't spent any diamonds, used a 2xncd, or burned any stamina other than what I accumulate throughout the day.
If they drop a 2x crafting, then I will use a 2xncd, and burn through some saved stam packs, and crush it. If they do not drop a 2x Crafting by Sunday, I'll slightly less crush it then, anyway.
