General note: voltage - tier formula
V = 2^(3+2T)EU/t
V = Voltage (EU/p or EU/t)
T = Tier (#)
Tiers:
0 = ULV = 2^3 = 8V
1 = LV = 2^(3+2) = 2^5 = 32V
2 = MV = 2^(3+4) = 2^7 = 128V
...
8 = UV = 2^(3+16) = 2^19 = 524288V
The exception to this pattern is MAX Voltage, where the voltage is equal to MaxInt (2^31 -1), the maximum number allowed in Java (without performing strange and dangerous dark magical arts).
