Okay, I'll try to simulate it somehow in an attempt to understand it more.
Anyway, your explanation leaves me with a question: why one onf the biggest
name in motorsports, one with "unlimited" R&D and resources,  is using an IC
and port WI if there is some free lunch in not using one and injecting water
earlier?
