No, it is the opposite.
Let us assume a 50 MVA generator with droop 4%:
A generator with Mbase equal to system base 100 MVA and droop 4%:
A generator with Mbase equal to system base 100 and droop 8%:
So,
R_system = R_machine * systemBaseMVA / machineBaseMVA
R_system = 4% * 100 / 50 = 8%
Droop is the inverse of gain (lower droop is higher gain), so the formula for conversion from Mbase to system base is also inversed!
