Do you mean "Phasers have a max range of 300,000m and suffer an addition -1 penalty for every "weapon range and accuracy" *100,000 meters?"Phasers:
Phasers gain a +2 mod to hit, and reduce the targeting penalty by one (so they are good at hitting specific stuff).
Phasers have a max range of 300,000m and suffer an addition -1 penalty for every "weapon range and accuracy" *100 meters. So a Galaxy class ship fireing phasers at a target 230,000m distant would get a -2 modifier.
A phasor hit does it's wattage x3 in damage.
So, firing phasers at 30,000 m would get no penalty, firing at 100,000 would get -1, and @ 200,000 would get -2?
