What are the green +numbers next to STR, AGI, and INT when promoting a character up to the next Star? I had assumed it was the new gains per level of each stat, but it appears I may be wrong in that assumption or there is a bug in the 6* to 7* promotion of Sidious. I just saw these screenshots in our LINE room that depicted this.
Darth Sidious Level 50 - 5* to 6* Promotion
STR 333 > 372 (+6.20)
AGI 566 > 634 (+9.40)
INT 309 > 343 (+5.20)
Darth Sidious Level 56 – 6* to 7* Promotion
STR 355 > 394 (+5.40)
AGI 595 > 650 (+8.00)
INT 366 > 399 (+4.50)
How are the starting stats less than the 6* Level 50 Sidious?
