I'm just curious, what size plane have you got? The reason I'm asking is the 1/2" of travel for the retract to fully cycle you mentioned, every 40 - 60 size mechanical retract I've delt with required 23 to 25 mm of travel. I remember reading an article here on RCU that described the proper way to set up mechanical retracts, I wished I had seen it when I set up my first set of retracts in 1993, I would probably have more hair now.
