DEar Taichi Kato, It may be because of the photographic observations taken during the 1913 outburst (see the composite light curves I made). There the maximum was brighter than the 1946/1978 outbursts, which was composed of mainly visual and photometric data. If understand correctly there's a difference of about 0.5 magntiude between photgraphic 'V' and photometric/visual 'V'. Also there's a spread in between visual measurements between different observers of up to 0.5 magnitude.
