As the title says it seems like there is a way to get back energy in zone mode after you lost it.
Maybe it's not a new thing and everyone knows it, but I didn't so I thought there may be others out there who don't as well.

As I already said: I noticed that you get back lost energy after a while in zone mode. I don't know if it's caused by a specific period of time or flying perfect or what ever but you definetely get it back.
I tried it on Mallavol and Syncopia and it worked for both.
I made screens to prove it. Look at the zones in the upper right corner and the energy bar that is changing it's status.


Mallovol:
01
02
03

Syncopia:
01
02
03


What I also noticed:
The energy bar design changes. Sometimes you can see the black line around it and the "+", sometimes you can't.


What do you think?
