What is definite for 21, 37 and 38 is it is impossible to achieve a 100% rate and that sparkling helps increase the rate. The effect of extra drums afaik has not been conclusively tested so it remains ambiguous.

Anyway, for the OP: I use 1.5x the required drums and 2 sparkled for 21 and 3 sparkled for 37/38 and all ships are 70+. I do not know exactly what effect each has but the great success rate is  about 80-90%.
