Tier 11 and 62% completion can be reached without upgrades. The reward is therefore 80%+100% = 50

E.G. The bottleneck currency is, all tiers and 84% completion of AWD Attack can be reached without upgrades. Only the last 100% reward of 21 can be won, with upgrades costing 175, therefore the reward for completing AWD Attack is 175 - 21 = 154 .
