On the top “official” note 0b0la is writing “nicer”. If the bottom notes are his, and I think it possible, his writing is more sloppy. I can write “nice” and sloppy and they look quite different, but handwriting experts can tell. A handwriting expert needs to get on this.
And compare with Bill Priestap’s handwriting and a half dozen random samples in a blind test. This proves nothing but confirmation bias.
