Subject: [bug?] Stadium and attendance

N 2367 seats under roof, 10 EUR
W 3854 benches, 8 EUR
E 3606 benches under roof, 8 EUR
S 2362 seats under roof. 10 EUR

Weather: partly cloudy
drizzle

The spectators' distribution for the benches considering the weather look weird to me.

Can anybody explain this?

I think the rules explain this more or less.
Fan preferences

Not every supporter likes the same type of stand. Some fans prefer seats, others benches, some others prefer terraces and others prefer to stand on the grass. If their favorite place is sold out they are likely to buy ticket for a superior stand but they will refuse to go to an inferior stand. Depending on the weather some supporter will buy a ticket only if a roof is available in his preferred stand.

I don't get it. How does this explain that benches under roof have a higher preference than benches without roof - especially under rainy weather conditions?

In case of benches vs benches under the roof from your case, it's probably rng which caused benches to "win". But I am guessing.

The difference is way too big for rng.

Roof over benches should minimize the loss of spectators due to rainy weather. This way it doesn't make any sence.

the only explanation I could imagine is that benches and benches under roof are two categories, and the benches were filled with spectators from terraces' category - not the benches under roof.
But that would be quite an odd basis for calculating.
I haven't noticed such odds with seats and seats under roof - maybe just because lower bench category was not sold out in those games.

I thought that the roof is just canceling the visitors' loss of bad weather for a specific category, i. e. benches.
