Table 6. Count of best ITIs.

Count of preferred ITIs in robustness simulations, using either single-molecule changes of ±10% or random changes (between +10% and −10%) to all molecules. 80% of the parameter variations yield optimal ppERK in response to spaced stimulation (ITI = 80 or 300 s).

ITIs	Random	10% lower	10% higher	Total percent
