RESEARCH - Upgrade Drop Rates Jul 2023

With the upcoming improvement in Elite drop rates, this documentary is to review the most energy-efficient approach to acquire upgrades.

Patch version: 1.9.1.416

Summary on efficiency

• Common:       Elite / Normal-5 (7% better) > Mirror > Normal-6
• Uncommon:  Elite (4% better) > Normal-5 (1% better) > Mirror > Normal-6
• Rare:               Elite (40% better) > Mirror > Normal
• Epic:               Elite (16% better) > Mirror > Normal
• Legendary:   Elite (30% better) > Mirror > Normal

• Note - % improvement is based on this formula:
• E.g. Common = (Mirror energy per unit- Elite energy per unit)/Elite energy per unit x 100%
• Note - there was a miscalculation in Rare %improvement in previous post. It is corrected here and will not be counted in as a change
• Note - 2 methods were involved leading to original results being wrong. Mitigation has been applied.
