Pendulum Color Battle Requirements

[swift heath]

On the pendulum color, to digivolve from IV to V, I need to do 15 battles and have an 80% win rate. If I have done that, do I need to do 15 MORE battles (30 battles total) and maintain my win rate to digivolve from V to VI, or have I already met the requirements?

Thank you 😄

From what I understand, you have to do the Battles again.

Same as the DMC
