    I've often heard the 15 - 20 % "rule of thumb".  Is this true regardless 
of HP?  If a 100hp vehicle lost 25hp, would a 500hp vehicle lose 125hp?  
Wouldn't it take roughly the same # of HP to drive similar Trans & rear end 
gears regardless of the HP of the engine?

    P.S.  Would a hand count necessarily yield a more accurate result?  ;-)
