I have tried to watch it, I find it odd. Like the boost they get for going over a certain piece of track, don't think there should be any fan boost.
I hate fan boost too. But "Attack Zone" is very clever: you get an extra 25kW of power twice during the race, for a limited amount of time. You have to use it twice, when you want. I much prefer this to DRS, because the extra power lasts during a few laps, not just in a straight line, and it adds an interesting strategic dimension to the race. And it works: the races have been very exciting this season.
