Good question! We haven’t specifically stress-tested our Engine this way, ie, having 1000 stimuli in one trial. I can foresee several problems arising as the amount of stimuli grow. Specifically, the initialisation phase could start taking very long, and the memory requirements of running a task could be too much for a user’s computer. But this would maybe start happening at around 10,000 stimuli per trial. Even so, the within-trial timing would not be affected too much, as the algorithm being used only handles the stimuli as a queue, and then only the previous, the current and the next stimuli in the queue. This way, timing shouldn’t be affected by the amount of stimuli in a trial.
As for the second part of your question.
There is some flexibility present in the current parser, related to the way the JSON configuration file is set-up. This feature is barely used, even by me, so I’d need to look into that again to see what’s possible.
