Plugin.json

[Raungale]

in the plugin.json file there is a point under stockcar rules, the double file. i have read on some internet sites that if you set it to 0, the single file comes into play with yellow flag and formation lap. i have always assumed that single file forms a row in a row aka assetto corsa competizione formation lap. but no matter what I change, the formation lap is always the same with cars next to each other. Or am I misunderstanding this option? Sorry for my english
