I rely on the Fast-90 method for all of my shots. However, the range comes into play at point-blank (< 500m/yds) and at extreme range (> 7000m/yds). I did some long calcs a while back and the float is only +/- 1.5 degrees. No big deal at point-blank, but the extra 1.5 degrees does matter at extreme range. Using ATAN (Target Speed/Torp Speed) to determine lead angle, subtract the 1.5 degree float for starboard-to-port targets and add the 1.5 float for port-to-starboard targets. My hit rate is around 75%, taking into account dud rates, possible aspect changes from the target and general weirdness. My longest range hit and kill is around 9km.
