Bow cam trivial / Blessed Faydark Stinger trivial

[metopu sureflight]

I know this will sound like an odd question. Can anyone explain why the trivial for a Blessed Faydark Stinger is less than that of other bows that use standard cams? If I am not mistaken isn't the trivial for using standard cams 190, where the trivial for the Faydark Stinger is only 156.

No clue, but not complaining myself - it's a nice little starter bow.
