That makes sense. I did not double count. I was just curious how the total displayed on the UI, which is 915000, was not reflected in my total credits.
I just completed 3 rounds of index at the lowest level. Went in with 3.2+ mil credits. Rewards say 915000 credits. But my total credit only went to 3.8 mil. The 285000 boosted credits seems missing.
Edit: Tried once more. Credits went up by 600000. Not the 915000 shown.
