Talk:Imperiali quota

Did Imperiali also invent 'his' quota or only the highest average method named after him?
Imperiali did propose the higest average method named after him (see his bill in 1920), but did he also invent the quota method named after him? I cannot find any primary source, any document by him proposing this quota system.Bancki (talk) 10:46, 22 January 2016 (UTC)
