LMDh - is the energy management realistic?

Im not a Pro thats why i ask:

In my knowledge the electrical power does not give extra boost in the actual HY Cars.
In LMU i have no boost, just fuel consumption reduction. In AMS 2 i have more power in Attack oder whatever mode.

What it realistic?

 

IDK which really IS realistic, but Renato said that they will make it more realistic in a future update

 

The LMU hybrid system is the realistic one & the virtual energy is like in the real WEC.

 

Michi Hoyer explained it for LMU

I hope this comes to AMS2 with the newly signed IMSA partnership. It matters much less with the LMDhs because the LMDhs are spec hybrid parts and the LMH cars have way more differences between them with the hybrids (with the Glickenhaus and Vanwall even being non-hybrid LMHs).

Still, I want to see this more realistic than less realistic.
