I had a quick question. In a recent tournament, I accidentally pissed off an opponent during the very first part of the psychic phase. I had a Hive Tyrant that flew up in range of a Ghost Ark and rolled for Warp Blast (Lance version) against the vehicle. I rolled 4 dice with 3 successes, and asked my opponent if he would like to deny the witch. He declined. I then waited for roughly 5 seconds while rolling the 1 dice in my hand for any type of response to my shooting attack. I then rolled a hit, then rolled a armour pen attempt which was successful, and immobilized the ark, ripping off the quantum shielding (total time was in the range of about 15-20 seconds from when I started to cast the psychic attack). He took that part with a disappointed look and stated that I did not give him enough time to state that he was jinking. I, for the rest of the game, asked him if he was jinking for every single shooting attack that I did to try to make up for it. This slowed the game down significantly. It was the first game, in years, that I have had even come close to the time limit.
I have grown used to, when stating that I am shooting at something that can jink, my opponent is chomping at the bit to tell me whether he is going to jink or not. This seems true, especially in the tournament setting.
My question: How long, after declaring a shooting attack, is it OK to assume that your opponent is refusing to jink and not just attempting to slow play?
I am legitimately curious.
Thank you for your time reading this.
