Following up on your question, @lucasbassoli26, about the TILLER_DEBTSNOWBALL() custom formula…

That custom formula is a script embedded into the Tiller Labs add-on.
Were you able to determine if the formula is behaving properly?

If you can help me understand specifically how it is (mis)behaving and what should be happening instead, I can improve it.

Thanks,
Randy
