The only thing that can be "timed" is the transfer bar. I once over stoned a trigger/hammer and no matter what I did (even jerking the trigger and holding back), I got light strikes, no strikes and some times it would fire. Every time the hammer would stay in it's cocked position, until I pulled the trigger. The only solution was to replace the trigger and hammer. So I would say the "timing" was not so good.
Adjusting the timing would be how high the transfer bar is when the hammer falls. In my case, the transfer bar was not coming up far enough to be between the hammer and the firing pin. I assume this is because when the trigger was pulled the hammer was falling too soon and not letting the transfer bar up far enough. When I changed out the hammer and trigger, I changed the timing. If I pulled the trigger all the way back, the transfer bar would go plenty high, but the hammer was falling before I got the hammer pulled far enough to get the transfer bar all the way up.
I know that many times it has been said in this forum to pull the trigger all the way back, even after the hammer falls. I think if the timing is good, that the lock time is so short that you can not get the hammer to fall and release the trigger in time to get the transfer bar out of the way. However, if the timing is poor, then pulling the hammer all the way back maybe needed to get reliable primer strikes. I think that this a bad situation and should be rectified. It has to effect accuracy, if you have to pull the trigger all the way back to get reliable primer strikes.
Good Luck and Good Shooting
