Narrative:

I was working local assist 2. We were busy with departures; and the tm (traffic manager) passed a strip for a smo departure (aircraft Y). After coordinating with the malibu sector I coordinated with smo and gave them a one minute heads-up; aircraft X started his takeoff roll and at the appropriate point I released the smo departure. The smo departure came off and we ended up with 2.75 between aircraft X and aircraft Y.I released the smo departure where I always do; but aircraft Y must have jumped on it as he got airborne and aircraft X must have been slow on his climb. I can give a little more room; but we had three more departures off of smo after aircraft Y; and I released them at the same point and the separation was adequate.
