Interestingly, run 3 takes an opposite approach, increasing 𝜖 for [#6:1] and decreasing 𝜖 for [#8:1] but achieving a similar reduction in bias. This suggests that, for the purpose of this optimization, [#6:1] and [#8:1] are treated as a unit. This is not desirable in a larger context, as these parameters are not inherently coupled and will probably lead to significant errors if used in different contexts.
