Challenge battle query

I read in https://answers.ea.com/t5/Game-Information/Challenge-Battles-are-Inconsistent/td-p/7099064 that "Unit levels should trigger Challenge Battles if the enemy's deck is 1.5 levels or more above on average"

In a recent match, my units were:

1. level 8 + 1 training
2. level 6 + 3 training
3. level 7 + 1 training
4. level 8 + 0 training
5. level 8 + 0 training
6. level 6 + 0 training

The other player had units of:

1. level 9 + ? training
2. level 9 + ? training
3. level 9 + ? training
4. level 9 + ? training
5. level 10 + ? training
6. level 10 + ? training

(screenshot attached)

Let's be conservative and assume the other player's units had no training, while bumping up to the next level any of my units that had training. This will underestimate the level difference.

• That would mean their total unit level is 9+9+9+9+10+10 = 56
• My total unit level is no more than 9+7+8+8+8+6 = 46

That's a total of at least 10 levels higher across 6 units, but it didn't trigger a Challenge Battle.

Note: my commander was level 7 + 0 training and theirs was level 9 + 2 training.

P.S. I really liked the updates from 1.1 onwards, and am particularly grateful that existing players were given the extra crates to bring everyone up to speed in the new league system.
