How each year is computed
(Diluted shares this year - diluted shares last year) / diluted shares last year x 100
Each year is a ratio of lines in that year's filed annual report, with the nightly recompute's own rules for what counts as a filed line. Nothing is estimated, smoothed or filled in: a year that cannot be computed says why.
