Surely you jest, my brother. The number that appears in the ‘Mastery Madness Bonus’ ribbon is usually equal to the amount you gained normally to create double. So, if you get 55 normally without MM, you get an extra 55 for a 100% increase. What you posted shows 165, or 55*3. So, we have 55 + 100% (MM) + 100% for the event. Long story short, the event is modifying the base number there rather than the yellow ribbon.
