Is this an official calculator?

No. It is an independent planner using only the numbers you enter.

What is simple payback?

Upgrade cost divided by the earnings increase you entered.

Does it know offline caps?

No. The scenario does not add an undisclosed cap or multiplier.

Why are there no worker presets?

Reliable worker names and rates are not publicly sourced yet.
