My previous question wasn't great, but I didn't want to ask this question without being sure that the kanji below the blue line is 会, but I'm assuming that it is.
In the above example, I've circled the parts that seem to be completely superfluous in blue, and in green I drew what I felt was the most natural flow between the strokes. Obviously calligraphy is supposed to be artistic/stylised but is it reasonable to just add extra strokes? The vertical stroke between ニ seems to be an extra stroke after 4th (judging by the flick upwards on the bottom stroke of ニ), and it seems to be connected to the bottom part. The ム seems almost to be reversed in how it's written, with some additional parts.
On the other hand, most calligraphy I've seen (including the 極真 above) seem to be much more faithful to stroke flow/direction. Is this just an outlier or is it expected that calligraphy takes such liberties in how kanji are written?
