That's clearly still not as quick as a Systema though. when I say the response on a PTW is instant it's because I mean it, I don't mean 'fast' I mean instant. Like real gun instant, the time it takes for a sear to break and a hammer to swing forward instant.
Whether you'd notice the difference while playing... that's by the by, like I said, you can get close but you'll never quite get there with an AEG gearbox without clever pre-cocking mosfets and even then it'll still be a couple of milliseconds slower than a PTW.
