This is helpful to exclude microfixations, which I-VT may classify as fixations but cannot be processed by humans:
The duration of 80-90 milliseconds is considered to be the shortest fixation that humans can control and process cognitively (Galley et al., 2015; Holmqvist & Andersson, 2017). Fixations shorter than that serve in the general perceptional process but the individual is unaware of them (Galley et al., 2015).
Furthermore, since we use intra_scope_window cut, this can also create fixations even smaller than 50... this would also catch those falsy fixations
