Just convert the MACH numbers to G's of acceleration, and things almost start to make more sense.
a less math intensive method would be as such.
read "mach" as Mark:
1 milli-Mark = 10 kilometers/hour
1 centi-Mark = 100 kilometers/hour
1 deci-Mark = 1,000 kilometers/hour
1 Mark = 10,000 kilometers/hour
1 deka-Mark = 100,000 kilometers/hour
1 hecto-Mark = 1,000,000 kilometers/hour
1 kilo-Mark = 10,000,000 kilometers/hour
1.8 kilo-Mark = speed of light = 18,000,000 kilometers/hour=1800 Mark
and accelleation/deccelleration would improve dodge bonuses (especially combined with other manuvers.) throw's off aim.
if:
(36kph/h x 60 x 60)/10000 = marks
129600 kph/h = 1g= 12.96 marks/h
so:
.1G= 1.296 marks/h
.2G= 2.592 marks/h -4 to dodge
.3G= 3.88 marks/h
.4G= 5.184 marks/h -3 to dodge
.5G= 6.48 marks/h
.6G= 7.776 marks/h -2 to dodge
.7G= 9.072 marks/h
.8G= 10.368 marks/h -1 to dodge
.9G= 11.664 marks/h
1G= 12.96 marks/h +/- 0 to dodge
1.1G= 14.256 marks/h
1.2G= 15.552 marks/h +1 to dodge
1.3G= 16.848 marks/h
1.4G= 18.144 marks/h +2 to dodge
1.5G= 19.44 marks/h
1.6G= 20.736 marks/h +3 to dodge
1.7G= 22.032 marks/h
1.8G= 23.328 marks/h +4 to dodge
1.9G= 24.624 marks/h
2G= 25.92 marks/h +5 to dodge
2.1G= 27.216 marks/h
2.2G= 28.512 marks/h +6 to dodge
2.3G= 29.808 marks/h
2.4G= 31.104 marks/h +7 to dodge
2.5G= 32.4 marks/h
2.6G= 33.696 marks/h +8 to dodge
2.7G= 34.992 marks/h
2.8G= 36.288 marks/h +9 to dodge
2.9G= 37.584 marks/h
3G= 38.88 marks/h +10 to dodge
please note that the next shot the ship in question fires will have the inverse of the dodge bonus for a To hit penalty.
so if a ship deccells for a +4 to dodge, the next shot it fires is at a -4 to hit. (since anything that throws off an enemies aim als will throw off your own.)
