Interactions:Credits on Garthic days?

So I know each interaction gives you 1-4 credits depending on a variety of factors. Does this apply to Garthic days? So today, for example, is +5. Does this mean there is an extra 5 interactions going towards credits count per click as well or purely your interaction score? Or is it just the base rate of credits?

Garthic gives extra Interaction Points. Nothing to do with Credits.
