Something wrong in ranolazine_mpo() ?

[CandyClass]

it says 'Make start_pop_ranolazine more polar and add a fluorine',
but the code is:
logP_under_4 = RdkitScoringFunction(descriptor=logP, score_modifier=MaxGaussianModifier(mu=7, sigma=1))
I guess logP_under_4 is a correct name stands for 'trying to minimize logP till its under 4', but the function uses MaxGaussianModifier with a mu=7, shouldn't that be MinGaussianModifier with a mu=4?
