Had a quick look and the sums seem ok.
If the output torque is 3.68 N.m then I think the required input torque is going to be four times that or about 10 N.m
If the input is 20rpm (= 0.7∏ rads/s) then I make the power required about
P = 0.7∏ * 10 = 22W
but just for the 0.25 seconds it takes to spin up.
Perhaps best design it assuming the current to your motor might spike to say 100W briefly to give plenty of margin?
