I was playing with Arena Score Calc

Byleth has 168 BST , 171 at +1
Robin has 149 BST, 172 at +10.

Why does Robin score more when their builds and BST are “the same” does anybody know?

The BST calc doesn’t account for merges beyond +1, so a +10 Robin and a +1 Robin both count as a 150 BST unit

And merges contribute more to score than BST. That’s the reason Robin still scores more.


If I recall each merge is worth 4 points.
