Metrics say percent – Double-check those decimals – Fractions everywhere
Picard metrics that say 'percent' actually mean 'fraction'. Let's take metrics from MarkDuplicates as an example. Under PERCENT_DUPLICATION we see 0.134008. If we divide READ_PAIR_DUPLICATES by READ_PAIRS_EXAMINED we get ~1/7 or 14%. Our sanity check makes clear the PERCENT_DUPLICATION metric is a fraction that translates to 13.4%.
