For some tasks, a sigmoid learning curve is used to model proficiency. Suppose the percent 100 proficiency is given by the model P(t) where t is days of practice. 1+80e-0.6t¹ = Find the inflection point, the point where additional practice starts producing diminishing returns. Give your answer accurate to at least 2 decimal places. days
