Common questions
Why does a slant disguise tend to fail on longer documents?+
Maintaining an unnatural slant takes conscious effort, and as the writer tires or loses concentration over a longer passage, habitual motor patterns reassert themselves and the disguise lapses.
What other features can expose a slant disguise?+
Letter formation habits, pen pressure, spacing, and stroke connections often stay closer to the writer's natural style even while the slant itself is being consciously altered.
