I suspect it’s by construction, looks like they’re offering every permutation of treat choice twice. Below, I filtered for A vs E, the top two choices. Notice how they switch left and right hand each time: A/E :: A E/A :: A A/E :: E E/A :: E A/E :: E |

The initial set-up was to do 3 comparisons of the 5 treats (30 trials), alternate between right and left hand, then write a quick python script to randomize the order.
A bit more than halfway through the experiment, I ran the model and realized that A/D/E were the only contenders left, so I removed the B/C trials and added more A/D/E trials.
