Description	When measuring intra-subject variability of eye movements, we often need to present trials repeatedly. In this experiment we studied, if we can use horizontally flipped trajectories of tracked objects and get similarly consistent eye trajectories. We presented each trial in two variants: L and R (horizontally flipped variant of L). Each variant was presented 6 times and each participant (N=26) was presented 5 different trials. Tracked objects moved in circular area with radius 15deg. We used Normalized scanpath saliency (NSS) metric for computing consistency of trajectories. Similarity of eye movements in within the same condition (NSS computed separately for L and R trials) was compared with mixed condition (NSS computed over trials sampled from both L and R trials). In the mixed condition we observed 14.7% decrease in eye movement consistency compared to the same condition and empirical baseline (similarity of individual eye movements across different trials). Those results are without any further corrections for gaze bias. When measuring intra-subject variability of eye movements, we often need to present trials repeatedly.
