If you are looking for a math solution to wattage, resistance, and voltage, the formula is Power = Voltage x Resistance. In technical circles the official formula is P=EI (power = voltage x resistance).
Those who use mechanical mods know the safety parameters for coil resistance and voltage. You are obviously using a power controlled
mod, so crank it up and down and stop when the flavor is to your liking.
Flavor is subject to a multitude of variables. Different juices show their flavor peak at different wattage levels, so there's no single answer to the question you asked.
