I dont think it will let you go into first unless you REALLY try, judging by the iron gate to the left of third...however, if it helps, my second-to-third stroke is angled slight to the right in open palm. not straight up | but slightly at an angle / (exaggerated) and its usually one unpaused stroke, sucks itself right into the gear.
I usually pass the third gear spring just as my foot bounces off the firewall, so I have maximum clutch depression and maximum syncro juice at the point of engagement in third. If you leave the throttle dipped a bit in, the motor revs will be just a bit higher, and the car's BEEFY clutch will grab quickly and the car will just keep accelerating.
It takes some practive, but after a few thousand k of 2-to-3 stroke snap shifts pull off wonderfully, just a constant torque stream.
Dont lift off completely on the throttle though....negative engine torque will cause some bucking.
After getting used to doing it this way, my old civic's clutch seems broken and I can barely drive that car anymore.
I've got third down pretty good but my second gear shift is still hit and miss. Sometimes its smooth torque transition sometimes I give it too much and the car lurches.. Bit off topic, sorry, I just kept typing.
