no prediction identities for first stimulus in ebmj

expect_equal(M$predict()[1], calc_pred(dt, pars, FALSE)[1], tol = tol)

if I test the first stimulus of a data set and we have no previously seen exemplars (i.e., the model has to guess), your model always renders 7.5 in my example. Why is this the case?
