I did a little math to see whether Pincushion helps to land Express Team critical knockdowns. I was expecting it to be slightly better, but was a bit surprised to see how much better!
function: crit ROLL:s drop lowest at least TARGET:n {
result: {1,2,3}@ROLL >= TARGET &
(1@ROLL = 2@ROLL | 1@ROLL = 3@ROLL | 2@ROLL = 3@ROLL)
}
output [crit 4d6 drop lowest at least 12]
This gives the following chances of hitting the KD on boosted shots using Pincushion (4D6-DL-C), and without Pincushion (3D6-C):
