I present three 3x4 designs I made for the AA callout.

The way you count piston door speed just changed, making every door officially 0.1s faster

First 3x4 : opening = 0.9s, opening reset delay = 0.1s, closing = 0.6s, closing reset delay = 0.2s

Second 3x4 : opening = 0.9s, opening reset delay = 0.1s, closing = 0.3s, closing reset delay = 0.2s

Third 3x4 : opening = 0.5s, seamless opening = 0.7s, opening reset delay = 0.1s, closing = 0.5s, closing reset delay = 0.5s
